Ai-c, ii-d, iii-a, iv-b ✓ Correct
Bi-a, ii-b, iii-c, iv-d
Ci-b, ii-c, iii-d, iv-a
Di-d, ii-a, iii-b, iv-c
Correct answer: (A) i-c, ii-d, iii-a, iv-b
Explanation
A dichotomous variable has only two categories, an independent variable causally affects another, a dependent variable is affected by another, and an interval variable has equal distances between categories.
A dichotomous variable takes exactly two values, such as yes or no.
An independent variable is the presumed cause manipulated by the researcher.
A dependent variable is the outcome that responds to the independent variable.
An interval variable has equal spacing between categories but no true zero.
The independent variable is plotted on the horizontal axis by convention.
