Show answer & explanation
Correct answer: C
Concept
Variables can be classified by their measurement structure or by their role in a causal model. A dichotomous variable has exactly two categories, while an interval variable has equal numerical intervals between adjacent values.
In a causal model, an independent variable is treated as the influencing or explanatory variable; the dependent variable is the outcome influenced by it.
Application
Dichotomous variable matches ‘has exactly two categories’, so A maps to III.
Independent variable matches ‘has a causal influence on another variable’, so B maps to IV.
Dependent variable matches ‘is causally influenced by another variable’, so C maps to I.
Interval variable matches ‘has equal distances between adjacent values throughout the scale’, so D maps to II.
Cross-check
The measurement-based descriptions are used once for dichotomous and interval variables, while the two causal-role descriptions are used once for independent and dependent variables. Thus every term and every description has a unique partner.
Therefore, the complete matching is (A)-(III), (B)-(IV), (C)-(I), (D)-(II).
