Measurement and Evaluation in Education: A Comprehensive Guide

Posted on Aug 8, 2024 in Psychology and Sociology

Introduction to Measurement and Evaluation

Measurement and evaluation are essential components of any effective learning system. While measurement focuses on assigning numerical values to attributes, evaluation involves making value judgments about performance or achievement. Both processes play crucial roles in improving the quality of education.

Measurement: The Foundation

Measurement involves assigning numbers to represent the degree to which an individual possesses a particular attribute. It quantifies how much a learner has learned. For example, a student’s score on an examination is a measurement of their academic achievement.

Meaning of Measurement

The term “measurement” originates from the Latin word “mensura,” meaning “the action of measuring something.” Accurate measurement is essential in education, as it allows us to objectively assess student progress and identify areas for improvement.

Concept of Measurement

Measurement is the assignment of a numerical value to an attribute of an object. The units used for measurement are often standard units, ensuring consistency and comparability.

Nature of Measurement

Effective measurement possesses several key characteristics:

• Quantitative: Measurement should be based on numerical data.
• Precise and Accurate: Measurements should be precise and accurate, minimizing errors.
• Reliable: Consistent results should be obtained when the measurement is repeated.
• Valid: The measurement should accurately reflect the attribute it is intended to measure.
• Objective: Measurement should be free from personal bias or subjective interpretations.

Characteristics of Measurement

In addition to the nature of measurement, several characteristics contribute to the effectiveness of measurement instruments:

1. Valid: The instrument measures what it is intended to measure.
2. Reliable: Consistent results are obtained when the instrument is used repeatedly.
3. Objective: The instrument is free from bias and subjective interpretations.
4. Usable and Practicable: The instrument is easy to administer and interpret.
5. Comprehensive and Precise: The instrument covers all relevant aspects of the attribute being measured.
6. Easy to Administer: The instrument is straightforward to use and manage.
7. Economical: The instrument is cost-effective to develop and implement.
8. Easy to Score: The instrument is simple to score and interpret.
9. Easily Available: The instrument is readily accessible to users.
10. Good and Attractive Getup: The instrument is visually appealing and engaging.

Scope of Measurement

Measurement plays a vital role in various aspects of education:

1. Prognosis: Measurement helps identify differences in student performance, facilitating classification, selection, promotion, and gradation. It also supports guidance and counseling services.
2. Diagnosis: Measurement helps identify student weaknesses and learning difficulties, enabling the development of remedial instruction.
3. Research: Measurement provides an objective and dependable basis for research, allowing for valid generalizations based on accurate data.

Functions of Measurement

The functions of measurement can be categorized into two major aspects:

1. Instructional Function: Measurement is used to determine the outcomes of teaching and learning processes and to make learning more effective.

• Principal Instructional Function: The basic purpose of measurement is to determine what knowledge, skills, abilities, habits, and attitudes have been acquired.
• Secondary Instructional Function: Measurement helps make teaching and learning more effective by supporting the formation of study habits, developing effort-making capacity, aiding guidance and counseling, and determining progress in learning outcomes.

Administrative and Supervisory Function: Measurement supports the effectiveness of instructional functions by maintaining standards, classifying or selecting students for special purposes, determining teacher efficacy, and serving as a basis for curriculum development.

Types of Measurement

Measurement can be categorized into different types based on the methods used:

1. Direct Measurement: This involves directly measuring the attribute of interest.

• Physiological Measures: These include measurements of heart rate, blood pressure, breathing rate, galvanic skin response, eye response, eye movement, and magnetic resonance imaging.
• Behavioral Measures: These involve observing and recording behaviors in naturalistic or laboratory settings.

Indirect Measurement: This relies on estimates or perceptions, often through indirect questions.

• Observer Estimates: These involve asking observers to provide their opinions or judgments about the attribute being measured.
• Indirect Questions: These involve asking individuals about their perceptions or experiences related to the attribute being measured.
• Unconstructive Measurements: These involve measuring changes in physical objects or environments, such as accretion or erosion.

Miscellaneous: This includes measurements based on archived or retrospective data.

• Archived Data: This involves using existing data, such as the number of emails sent from students to instructors.
• Retrospective Data: This involves collecting data about past events, such as employee absenteeism or turnover rates.

Measurement Scales

Measurement scales classify data based on their properties and characteristics. There are four main scales of measurement:

1. Nominal Scale: This scale categorizes variables into distinct, non-ordered categories or labels. Examples include gender, marital status, and types of trucks.
2. Ordinal Scale: This scale categorizes variables into ordered categories, but the differences between categories may not be equal. Examples include educational levels, Likert scale responses, and rank order.
3. Interval Scale: This scale maintains the ordered categories of the ordinal scale but also has equal intervals between consecutive points. However, there is no true zero point. Examples include temperature measured in Celsius or Fahrenheit and calendar years.
4. Ratio Scale: This scale possesses all the properties of the interval scale, but it also has a true zero point, which signifies the absence of the attribute being measured. Examples include height, weight, time (in seconds), and money.

Role of Measurement in Education

Measurement plays a crucial role in various aspects of education, including:

1. Determining Goals: Measurement helps educators set clear and measurable goals for student learning.
2. Development and Improvement: Measurement and evaluation contribute to improving student learning by identifying problems, clarifying needs, and determining progress.
3. Diagnosis and Solutions: Measurement helps identify student strengths and weaknesses, enabling educators to address learning difficulties.
4. Categorizing Students: Measurement helps classify students based on their skills and abilities, facilitating appropriate placement and instruction.
5. Guidance and Instruction: Measurement provides valuable information for educational counselors, enabling them to make informed decisions about student guidance and support.
6. Feedback: Measurement provides feedback to teachers, students, and the entire educational system, promoting continuous improvement.

Evaluation: Making Value Judgments

Evaluation goes beyond measurement by making value judgments about performance or achievement. It involves interpreting data and making decisions based on the information gathered.

Meaning of Evaluation

The term “evaluation” originates from the Latin word “valupare,” meaning “the value of a particular thing, idea, or action.” Evaluation involves determining the worth or significance of something.

Definition of Evaluation

According to James M. Lee, “Evaluation is the appraisal of pupils’ progress in attaining the educational goals set by the school, the class, and himself. The chief purpose of evaluation is to guide the students for further learning. Evaluation is a positive rather than a negative process.”

Concept of Evaluation

Evaluation involves collecting, analyzing, and interpreting information about any aspect of an educational program to judge its effectiveness, efficiency, and other outcomes.

Nature of Evaluation

Evaluation is a science of providing information for decision-making. It encompasses measurement, assessment, and testing. The evaluation process involves:

• Information Gathering: Collecting relevant data about the program or aspect being evaluated.
• Information Processing: Analyzing and interpreting the collected data.
• Judgment Forming: Making value judgments based on the analysis of the data.
• Decision Making: Using the evaluation findings to make informed decisions about the program or aspect being evaluated.

• Prepare for Future Life: CCE equips students with life skills, such as critical thinking, social skills, and coping skills.
• Learner-Friendly Environment: CCE promotes a learner-friendly environment that optimizes student learning.

Grading System

A grading system is a system used to assess the educational performance of students based on points and assign grades, typically using letters or numbers.

Features of Grading

• Classification: Student performance is classified into a few categories using letter grades or numerical ranges.
• Point Scale: Grading systems typically use a point scale, such as a 5-point, 7-point, or 9-point scale.
• Score: Grades represent a score or level of achievement.
• Performance Level: Grades identify student performance levels within a wide range.
• Specialized Symbols: Grading systems use specialized symbols, such as letters or numbers, with objectively defined meanings.

General Classification of Grading

• Percentage Grading: Grades are assigned based on a percentage scale from 0 to 100.
• Letter Grading: Grades are assigned using letters, such as A, B, C, D, and F.
• Norm-Referenced Grading: Grades are assigned based on student performance relative to their peers.
• Mastery Grading: Students are graded as”master” or passers when they reach a predetermined level of proficiency.
• Pass/Fail: Students are graded as either”pas” or”fail”
• Standards Grading: Grades are assigned based on student performance relative to pre-established standards or criteria.
• Narrative Grading: Written comments are provided about student performance, rather than assigning numerical or letter grades.

Types of Grading

1. Direct Grading: Grades are assigned directly based on the evaluator’s judgment of student performance, without assigning numerical scores.
2. Indirect Grading: Grades are assigned based on numerical scores, which are then converted to letter grades.
3. Absolute Grading: Grades are assigned based on a fixed set of standards or criteria, regardless of student performance relative to their peers.
4. Relative Grading: Grades are assigned based on student performance relative to their peers, using a normal probability curve.

Basic Characteristics of a Good Measuring Instrument

A good measuring instrument should possess several key characteristics:

1. Reliability: The instrument should consistently produce similar results when used repeatedly under similar conditions.
2. Validity: The instrument should accurately measure the attribute it is intended to measure.
3. Objectivity: The instrument should be free from bias and subjective interpretations, ensuring that different evaluators would assign similar scores to the same performance.

Scales of Measurement

Scales of measurement, also known as levels of measurement or types of variables, are classifications that indicate the nature and characteristics of the data being collected. These scales help researchers understand the properties of the variables they are working with, which in turn informs the appropriate statistical analyses and interpretations. There are four main scales of measurement: nominal, ordinal, interval, and ratio.

Nominal Scale

The nominal scale is the simplest level of measurement, where variables are categorized into distinct, non-ordered categories or labels. Examples include gender, marital status, and types of trucks.

Ordinal Scale

In the ordinal scale, data are categorized into ordered categories, but the differences between categories are not equal. Examples include educational levels, Likert scale responses, and rank order.

Interval Scale

The interval scale maintains the ordered categories of the ordinal scale but also has equal intervals between consecutive points. However, there is no true zero point. Examples include temperature measured in Celsius or Fahrenheit and calendar years.

Ratio Scale

The ratio scale possesses all the properties of the interval scale, but it also has a true zero point, which signifies the absence of the attribute being measured. Examples include height, weight, time (in seconds), and money.

Conclusion

s made from the test. We usually refer to these types of tests as standardized.

• The data is mathematically computer and summarized. Scores such as percentiles, stanines or standard scores are mostly commonly give from this type of assessment. 

2. INFORMAL ASSESSMENT : 

• Informal assessments are not data driven but rather content and performance driven. For example, running records are informal assessments because they indicate how well a student is reading a specific book. Scores such as 10 correct out of 15, percent of words read correctly, and most rubric scores are given from this type of assessment.

3. FORMATIVE ASSESSMENT

• “A diagnostic use of assessment to provide feedback to teachers and students over the course of instruction.” Carol Boston

• gathering of data during a time program is being develop. This is likewise provide feedback for the improvement of an instruction or for the improvement of the program.

4. Summative assessment :

• “A summative assessment is one attempts to assess student learning for a specific time period. For example, a unit test would be a summative assessment.” Ralph Eden

• Use to determine the mastery & achievement of the student.

• Done usually at the end of a chapter or unit.

• Accountability of success or failure.

• Use primarily in assigning grades.

• Designed to determine the extent to which the instructional objectives has been achieved.

• The goal of summative assessment is to evaluate student learning at the end of an instructional unit by comparing it against some standard or benchmark.

PURPOSE OF ASSESSMENT : 

• To diagnose students’ strengths and weaknesses.

• To assign grades.

• To determine the teachers’ effectiveness.

• To monitor students’ progress.

• To help evaluate teachers.

Evaluation: 

• Evaluation is concerned with a whole range of issues in and beyond education; lessons, programs, and skills can be evaluated. It produce a global view of achievements usually based on many different types of information such as observation of lessons, test scores, assessment reports, course documents or interviews with students and teachers.

• The process of making overall judgement about one’s work or a whole school work (Cameron)

• Evaluation is a process of determining to what extend the educational objectives are being realized — Ralph Taylor

NEED AND IMPORTANCE OF EVALUATION :

Evaluation is a broader term than the measurement. It is more

comprehensive than mere measurement. It is more inclusive than the term measurement. It goes ahead of measurement which simply indicates the numerical value. It gives the value judgment to the numerical value. It includes both tangible and intangible qualities.

Therefore evaluation is much more comprehensive and inclusive term than measurement and test. A test is a set of questions, measurement is assigning numbers to the results of the test according to some rules o the other hand evaluation adds value judgment. Therefore evaluation includes both quantitative description (measurement) and qualitative description (non-measurement) along with value judgments.

The main aim of teaching learning process is to enable the pupil to achieve intended learning outcomes. In this process the learning objectives are fixed then after the instruction learning progress is periodically evaluated by tests and other evaluation devices.

The need and importance of evaluation can be perceived in the

following ways : 

• Evaluation helps in preparing instructional objectives.

• Evaluation process helps in assessing the learners’ needs.

• It helps in providing feedback to the students.

• It helps in preparing programmed materials.

• It helps in curriculum development.

 • It helps in reporting pupils’ progress to the parents.

• Evaluation data are very much useful in guidance and

counseling.

• It helps in effective school administration.

• Evaluation data are helpful in school research.

PURPOSE OF EVALUATION :  

A comprehensive scheme of educational evaluation serves a number of purposes that ultimately contribute to the improvement of the instructional methods, text books, curriculum and even an advancement of our educational goals. “Education helps us to set tasks and goals which are higher than what we aspired for earlier, thus giving leadership in education” broadly speaking the purposes of evaluation can be categorized into two kinds, Educational and administrative.The educational purpose of evaluation are primarily concerned with quality control in relation to

A) The Learning: This includes such functions as monitoring student

progress, diagnosing student weakness, determining the need for

remedial work, and improving the quality of the learning environment.

B) The Teaching: This is concerned with assessing the effectiveness

of teaching, the teaching strategies, methods and techniques.

C) The curriculum: This includes improving courses and curricula,

texts and students and teacher’s materials.

The administrative purposes of evaluation include accountability to:

 a) Society: This includes accountability to society in terms of the

demands and requirements of the employment market.

 b) Parents: This mainly manifests itself in a perceived need for

regular reporting to parents about the progress of their children.

 c) Educational system: This includes the requirements of

educational system itself for purpose of selection of students for

various courses, such as for entrance to higher grade or tertiary level.

Types of evaluation : 

1. PLACEMENT EVALUATION 

Placement evaluation is concerned with the pupil’s entry

behavior and typically focuses on questions such as the following

(1) Does the pupil possess the knowledge and skills needed to begin

have a sufficient command of computational skills? (2) To what extent

has the pupil already mastered the objectives of the planned

instructions? Sufficient mastery might indicate the desirability of the

pupil’s skipping certain units or of his being placed in more advanced

course. (3). To what extent do the pupil’s interest, work, habits and

personality characteristics indicate that one mode of instruction might

be better than another e.g. group instruction versus independent study.

Answers to questions like these require the use of a variety of

techniques; readiness tests., aptitude tests, pre-tests on course

objectives, self-report inventories, observations techniques and so on

The goal of placement evaluation is to determine the position in the

instructional sequence and the mode of instruction that are most likely

to provide optimum achievement of each pupil.

2 FORMATIVE EVALUATION

As noted earlier, formative evaluation is used to monitor

learning progress of students during instruction. Its purpose is to

provide continuous feedback to both pupil and teacher concerning

learning successes and faults. Feedback to students provides reinforcement of successes of learning and identifies the specific learning error that needs correction. Feedback to the teacher provides information for modifying instruction and for prescribing group and individual work. Formative evaluation depends heavily on specially prepared test for each segment of instruction (e.g., Unit Chapter).

These are usually mastery tests that provide direct measures of

all the intended learning outcomes of the segment prescriptions for

alternative of remedial instruction are typically keyed to each item in

the test or to each set of items measuring a separate skill. Tests used for formative evaluation are most frequently teacher-made, but customized testes (tests made to order by publishers ) can also useful in monitoring pupil progress and identifying learning errors. Since formative evaluation is directed toward improving learning and instruction the

results are typically not used for assigning course grades.

3. DIAGNOSTIC EVALUATION

Diagnostic evaluation is concerned with the pupil’s persistent or recurring learning difficulties that are left unresolved by the standard corrective prescriptions of formative evaluation. if a pupil continues to experience failure in reading, mathematics. or other subjects. Despite the use of prescribed alternate methods of instruction (e.g. programmed materials visual aids). Then a more detailed diagnosis indicated. To use a medical analogy, formative evaluation provides first aid treatment for simple learning problems, and diagnostic evaluations searches for the

underlying causes of those problems that do not respond to first aid treatment. It involves the use of specially prepared diagnostic tests as

well as various observational techniques. Serious learning problems are also likely to require the services of remedial, psychological and

medical specialists. The primary aim of diagnostic evaluation is to determine the causes of learning problems and to formulate a plan for remedial action.

4. SUMMATIVE EVALUATION

Summative evaluation typically comes at the end of a course(or unit) of instruction. It is designed to determine the extent to which the instructional objectives have been achieved and is used primarily for assigning course grades or for certifying pupil mastery of theintended learning outcomes. The techniques used in summative

evaluation are determined by the instructional objectives, but they

typically include teacher made achievement tests ratings on various

types of performances (e.g. laboratory, oral report). Although the main

purpose of summative evaluation is grading, or the certification of pupil

mastery, it also provides information for judging the appropriateness of

the course objectives and the effectiveness of the instruction.

5. Criterion-referenced evaluation :

Criterion referenced evaluation are designed to measure student performance against a fixed set of predetermined criteria or learning standards-i.e., concise, written descriptions of what students are expected to know and be able to do at a specific stage of their education. (fail or pass only)

Characteristics of criterion referenced test :

• Its main objective is to measure student’s achievement of curriculum based skills.

• It is balanced representation of goals and objectives.

• It is used to evaluate the curriculum plan instruction progress and group students interaction.

• It can be administrated before and after instruction.

• It is generally reported in the form of minimum scores, number of correct items, percent of correct items and derived score based on correct items and other factors. 

Uses of CRT : 

• To discover the inadequacies in learners learning and assist the weaker section.

• To identify the master learners.

• Find out the level of attainment of objectives.

• To find out the level at which a particular concept has been learnt.

• To better placement of concepts at different grade levels. 

Limitations of CRT : 

Chase (1974) lists the following limitations : 

• Does not show how good or poor is the learners level of ability.

• Influenced by a given teachers interest or biases.

• Important for only a small fraction of important educational achievement.

6. Norms Referenced evaluation :

• Norm-referenced evaluation is the traditional class-based assignment of numerals to the attribute being measured. It means that the measurement act relates to some norm, group or a typical performance. It is an attempt to interpret the test results in terms of the performance of a certain group (relative position in a group)

• Examples of norm-referenced tests include the SAT, IQ tests, and tests that are graded on a curve.

Characteristics of NRT : 

• Its basic purpose is to measure students achievement in curriculum based skills.

• It is prepared for a particular grade level.

• It is administrated after instruction.

• It is used for forming homogeneous or heterogeneous class groups.

•It classifies achievement as above average, average or below average for a given grade.

• Reported in the form of Percentile rank, linear standard score.

Uses of NRT : 

• It is useful in making aptitude testing

• To get reliable rank ordering of pupils.

• To identify the pupils who have mastered.

• Select best of the application for a particular programme

• For effective comparison of other possible programme

Limitations of NRT : 

• There is lack of congruence between what the test measures.

• Test items that are answered correctly by most of the pupils are not included.

• Promotes unhealthy competition.

Continuous & Comprehensive Evaluation (CCE) : 

Continuous and Comprehensive Evaluation (CCE), recommended as a school-based system of evaluation by different policy documents from time- to-time and mandated under Section 29(2) of the Right of Children to Free and Compulsory Education (RTE) Act-2009, can be an effective and potent tool, to help teachers, parents/guardians and children themselves take charge of the learning and development.

Continual aspect refers to the assessment of learners’ progress on various aspects from the very beginning of instructions, (placement evaluation) till end i.e. summative evaluation.

Characteristics of Continuous Evaluation : 

1) Continuous evaluation is formative in nature and is school based. It is to be carried out by teachers teaching a particular class.

2) The purpose of continuous evaluation is mainly improvement in learning. For this the learning gaps and weaknesses are diagnosed so that feedback can be provided.

3) Continuous evaluation is informally carried out in the classroom; there is no need of making lengthy arrangements required for a formal examination like preparation and administration of question papers, seating arrangement, etc.

4) Multiple techniques of evaluation need to be used for continuous evaluation. These include not only written tests, but oral tests, quizzes, assignments, projects, observation, peer evaluation, self appraisal, etc.

5) Continuous evaluation is built into the total teaching-learning programme and is a part of the daily routine for a teacher.

Nature of Continuous and Comprehensive Evaluation : 

• The nature of CCE is so comprehensive that it includes almost all aspects of child development.

• It integrates assessment with teaching and learning process; emphasizing assessment of learner abilities in scholastic areas along with the co- scholastic areas.

• CCE encourages and motivates students to be positive in their attitudes.

• It emphasizes that teacher’s judgment should be made through an honest and objective appraisal without bias.

• It also encourages continuous interaction with parents with regard to their children’s progress and performance.

• CCE is developmental in nature because emphasis is given on improvement of students’ learning throughout the schooling process.

• It is a process of continuous attempts to assess whether desirable changes are taking place in students along the lines of educational objectives.

Purposes of Continuous and Comprehensive Evaluation : 

• CCE emphasizes evaluation as a process in place of an event.

• CCE helps learners, parents and teachers in the following ways:

• It reduces stress and anxiety, which often builds up among the young students during and after the examination.

• It reduces the dropout rate as there will be less fear and anxiety among learners related to their school performance.

• In CCE, greater focus is given on learning rather than on conducting tests and examinations.

• It contributes to the holistic development of learners.

• CCE is used as an instrument of preparing learners for future life by making them physically fit, mentally alert, emotionally balanced and socially adjusted.

• Learners get more time to develop their interests,hobbies and personalities through CCE.

• It promotes a learner friendly environment, thereby optimizes student learning.

• It equips students with life skills, especially creative and critical thinking skills, social skills and coping skills which will help them to face a highly competitive environment later on.

Grading system : 

•The grading system is the process by which educators evaluate the performance of the G pupils in exams on the standard particular scales which is based on the points entirely and consist of the grades like A-F or range like 1-10; generally, letters and numbers are used to describe the grades of the scholars

• A grading system in education is a system that is used to assess the educational performance of a child which is entirely based upon points alone. 

Features of grading : 

• When students level of performance are classified into a few classificatory units using letter grade, system of assessment is called grading system.

• In grading classification is made on 5 point, 7 point, 9 point scale.

• It is a score

• It identifies students performance level with a wide range

• It involves the use of set of specialized symbols whose meaning ought to be objectively defined in terms of specific criteria.

General classification of grading :

• Percentage Grading – From 0 to 100 Percent

• Letter grading and variations – From A Grade to F grade

• Norm-referenced grading – Comparing students to each other usually letter grades

• Mastery grading -Grading students as “masters” or passers when their attainment reaches prespecified level

• Pass/Fail-Using the Common Scale as Pass/Fail 

•Standards grading (or Absolute-Standards grading or Criterion Referred grading) – Comparing student performance to a pre-established standard (level) of performance

• Narrative grading-Writing Comments about students

Types of grading : 

1. Direct grading:

• Judgment of any given phenomenon (achievement) skills, personality traits the evaluator in items of most appropriate letter grade without assigning the scores.

• In examination, the evaluator will award a particular grade to the answer for each individual questions on the basis of its quality.

• The Grade Point Average (GPA) calculated for obtaining the overall grade of the student in a particular subject

2. Indirect grading : 

• Method of awarding grades through marks.

• Marks are awarded to the individual questions on the basis of the prescribed marking scheme.

• Find out the total mark and convert to grade

3. Absolute grading : 

• Based on a definite set of standard when.bu evaluating a student’s performance

• Based on teachers pre-specifying standard for performance.

• Based on criterion referenced, and keep tasks mind without any variability.

• Some fixed range of scores are determined in advance for each grade.

• The score obtained by a student in a subject converted.

4. Relative Grading:

• It ids based on how a student’s performance compared to others in the group/class.

• It is norm referenced and focus on the vari in the quality of students.

• The grading range is not fixed in advance.

• It shows a normal probability curve

Basic characteristics of a good measuring instruments: 

1. Reliability-

The reliability of the test refers to the consistency of scores obtained by the same individual at different occasions.

1st day scores obtained -47 After 7 days scores obtained for the same test -47. 

Factors affecting The reliability : 

• Length of the test -If length is more Reliability is high.

• Range of respondents ability -if it is greater, reliability is high.

• Span of age group of respondents- If It is large, reliability is high.

• Method of determining the reliability.

• Time span between two tests- If it is greater, then the reliability is less.

• Way of evaluating the answers sheet-If it is objective, then the reliability is high.

• Difficulty level high-Reliability is less.

• Language of the questions-If the language is difficult, reliability is less.

• The way of answering -If it is done by guessing, then the reliability is less.

• Environment -It also affects the validity.

• Optional questions-If optional questions are given, reliability reduces.

2. Validity :

• Validity is the authenticity of the test.

• The test should measure what it supposed to be measured.

• If any test is fulfilling its objective then that is called as the valid test.

• The concept of validity was formulated by Kelly (1927, p. 14) who stated that a test is valid if it measures what it claims to measure.

• For example a test of intelligence should measure intelligence and not memory.

Factors affecting Validity-

• Culture,

• Ambiguous instructions.

• Low level questions.

• Medium of the Test (Language-whether mother tongue or not))

• Questions based on the objective or not.

• Improper variables.

• Bias.

•Time given Way of answering. (By making guess or not) Language of the test. (Easy, understandable of not)

• Difficulty level.

• Evaluation method- objective/subjective

3. Objectivity : 

•Absence of subjectivity is nothing but objectivity.

• there should not be any change in the scores when the test is evaluated by different supervisors.

• To find out objectivity, the test is checked by two different supervisors & coefficient of correlation is found out.

Scales of measurement : 

Scales of measurement, also known as levels of measurement or types of variables, are classifications that indicate the nature and characteristics of the data being collected. These scales help researchers understand the properties of the variables they are working with, which in turn informs the appropriate statistical analyses and interpretations. There are four main scales of measurement: nominal, ordinal, interval, and ratio. 

1. Nominal Scale:

• Definition: The nominal scale is the simplest level of measurement, where variables are categorized into distinct, non-ordered categories or labels.

• Examples: Gender (male, female), Marital status (single, married, divorced), Types of truck)

• Characteristics:

• Categories are mutually exclusive and exhaustive.

• There is no inherent order or ranking among categories

• Mathematical operations (e.g., addition, subtraction)

2. Ordinal scale : 

• Definition: In the ordinal scale, data are categorized between the categories are not equal.

• Examples: Educational levels (elementary, high school,college ), likert scale responses (strongly disagree, disagree,neutral, agree, strongly agree), Rank order (1st place,2nd ace,3rd place) 

• Characteristics:

• Categories have a meaningful order ranking.

•,Differences between categories may not be consistent or measurable.

• Relative positioning is known,but the magnitude of differences is not.

3. Interval Scale: 

• Definition: the interval scale maintains the ordered categories of the ordinal scale but also has equal intervals between consecutive points . However, there is no true zero point.

• Example : Temperature measured in celsius or Fahrenheit, Calendar years (e.g., 2021, 2022, 2023).

• characteristic : 

• Equal intervals between points.

• Absence of a true zero point; zero does not indicate the absence of the attribute.

• Addition and subtraction operations are meaningful, but multiplication and division are not.

4. Ratio Scale:

• Definition: The ratio scale possesses all the properties of the interval scale, but it also has a true zero point, which signifies the absence of the attribute being measured.

Examples: Height, Weight, Time (in seconds), Money.

• Characteristics :

• Equal intervals between points

• Presence of a true zero point, where zero indicates the absence of the attribute.

•All arithmetic operations (addition, subtraction, multiplication, division) are meaningful.
