Social Research: Design, Objectives, and Approaches
Research Design
Coming to the planning of research to find out something scientific, you must design a strategy. For this, you must:
- Specify exactly what you want to find out.
- Decide how best to do it.
You have to make observations and interpret what has been observed. But before this, you must have a plan. You have to decide what is to be observed and analyzed: why and how. Herein is research design.
Research Objectives
Social research can have many goals, but three of the most common and useful are:

Process Costing System
Process Costing Example:
Company ”Alfa” produces product ”Y” through two production phases: assembly and testing. At the beginning of 200X, there was no work-in-progress balance. During 200X, they started production of 800 units of product ”Y”. Of these, 350 units were finished at the end of the period, and 450 units remained in the production process. All 450 unfinished units of product ”Y” have passed the assembly phase and are in the testing phase.
During 200X, the

Prepositions with Nouns
Dependant Prepositions (Preposition + Noun)
In theory, in practice, in advance, on purpose, by heart, at the latest, by chance, on the news (referring to a specific item), in the news (these days, generally), in a very bad mood, in the end (at last, finally), by mistake, for nothing, on good terms, on principle, in principle, in debt, against the law, as a rule.
Dimensional Accuracy
Key concepts: precision and tolerance, size, shaft, bolt.
- Allowed/Permissible: Acceptable variations.
Basic Geometric Concepts and Definitions
Magnitude
Magnitude: A property of objects, considered individually with respect to other properties it may have. It is required to be measurable, in the sense that it is possible to represent it by numbers.
Extensive vs. Intensive Magnitudes
- Extensive: It is possible to define the sum between different quantities of that magnitude, and that operation verifies certain properties (opposite element, associative, commutative, neutral element) (e.g., length, speed).
- Intensive: The sum operation does not
Understanding Financial Investments: Types, Maturity, and Profitability
Financial Function: Investing
An investment is an allocation of resources with the expectation of future benefit. This involves acquiring an asset with the hope that its value will increase or generate income.
Types of Investments
Investments can be classified in several ways:
- Asset vs. Asset Investments: Distinguishing between investments in different types of assets. Companies often consider investments in complementary assets and fixed assets.
- Financial vs. Productive Investments: Financial investments
Mastering Linear Equations: Forms, Slope, and Intercepts
Forms of Linear Equations
1. Slope-Intercept Form
This form is represented as:
y = mx + b
- m = slope (rise/run)
- b = where the line crosses the y-axis (y-intercept)
How to Use:
- Start at b (on the y-axis).
- Use the slope (rise/run) to plot more points.
Example:
If m = 2 and b = -3, the equation is:
y = 2x – 3
2. Point-Slope Form
This form uses:
y – y₁ = m(x – x₁)
- m = slope
- (x₁, y₁) = a point on the line
Steps to Convert to Slope-Intercept Form:
- Start with the formula: y – y₁ = m(x – x₁)
- Distribute (multiply)
