Research Variables Statements Analysis
This section analyzes the correctness of statements regarding different types of variables used in research, specifically focusing on their definitions and roles in experimental and quasi-experimental contexts.
Statement Breakdown
- A. Continuous Variable: This statement is correct. A continuous variable, like 'Age', can take on any value within a given range, and its precision is limited only by the measurement tool. For example, age can be measured in years, months, days, or even fractions thereof.
- B. Extraneous Variables: This statement is incorrect. Extraneous variables are any variables that could potentially influence the dependent variable in a study. They are not necessarily 'macro level' or 'hidden'; they are simply factors other than the independent variable that might affect the outcome.
- C. Dependent Variable: This statement is correct. The dependent variable is considered the outcome variable, meaning it is influenced by or is a result of changes in the independent variable. It's what the researcher measures to see the effect.
- D. Independent Variable: This statement is correct. In experimental research, the independent variable is the variable that the researcher actively manipulates or changes to observe its effect on the dependent variable.
- E. Confounding Variables: This statement is incorrect. Confounding variables are a type of extraneous variable that influences both the independent and dependent variables, thus distorting the relationship between them. They are not the dependent variables themselves within quasi-experimental designs or any other design.
Identifying Correct Statements
Based on the analysis:
- Statement A is correct.
- Statement C is correct.
- Statement D is correct.
Therefore, the combination of correct statements includes A, C, and D.

Given below are two statements: one is labelled as Assertion A and other is labelled as Reason R
Assertion A: Experimental research allows you to eliminate the influence of many extraneous factors.
Reason R: In experimental research variables are actively manipulated and environment is as controlled as possible
