Variable Matching Solution
This solution matches the variables listed in LIST-I (Type of Variable) with their corresponding natures in LIST-II.
Understanding Variable Definitions
- A. Dependent Variable: This is the variable that is observed and measured. It represents the assumed effect of a change, often influenced by the independent variable. It corresponds to II. Assumed effect of change.
- B. Connecting Variable: This type of variable acts as a bridge, linking the independent and dependent variables. It is often an intervening or mediating variable, essential for explaining the causal link. It matches I. Necessary in certain situations to complete cause-effect relations.
- C. Extraneous Variable: These are variables other than the independent variable that could potentially affect the dependent variable. They are typically not measured directly in the primary analysis but can influence the strength of the relationship between the main variables. It corresponds to III. Not measured but may increase or decrease the magnitude of relationship between Independent and Dependent variable.
- D. Independent Variable: This is the variable that is manipulated or changed by the researcher. It is considered the presumed cause of change in the dependent variable. It matches IV. Assumed cause of change.
Final Matching
Based on these definitions, the correct matching is:
- A - II
- B - I
- C - III
- D - IV
This corresponds to the option: A-II, B-I, C-III, D-IV.

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
