Assessment Tools for Literacy and Cognitive Development in Children
Tests
1. Basic Functions Test – PFB
Authors
Neva Milicic and Olga Berdicewski (1974)
Objective
To assess the degree of maturity reached by the child to start learning reading and writing. Establishing a prognosis with regard to the time the child could delay the acquisition of reading and writing. Organize classes for children with differential immaturity.
Addressee
Primarily children who have completed kindergarten or newly initiated 1st grade.
Structure
Consists of 8 subtests: copying figures, visual memory,

Regression
Regression is a well-known statistical technique used to model the predictive relationship between several independent variables (DVs) and one dependent variable. The objective is to find the best-fitting curve for a dependent variable in a multidimensional space, with each independent variable being a dimension. The curve could be a straight line, or it could be a nonlinear curve. The quality of fit of the curve to the data can be measured by a coefficient of correlation (r), which is

Sampling Methods and Concepts
Sampling Error
Any difference between the characteristics of a sample and the characteristics of a population. The larger the sampling error, the less representative the sample.
Target Population
A set of elements larger than or different from the population sampled and to which the researcher would like to generalize study findings.
Representative Sample
A sample that “looks like” the population from which it was selected in all respects that are potentially relevant

Measures of Central Tendency and Variability
Nominal, Ordinal, Interval, and Ratio Scales
Nominal = qualitative number, categories, no numerical relationship between categories, Ordinal = ranking of categories, do not know how much greater each category is, Interval = continuous (magnitude difference between two values can be determined), placement of zero is arbitrary (e.g., Celsius), Ratio = continuous, zero has a natural interpretation
Sampling Distribution
A sampling distribution is a probability
