Question

Quizplus · Accepted Answer

A variable is defined as something that can have more than one value or score. It is a measurable attribute that can differ across individuals, groups, or over time. Option A is too broad and does not fully capture the meaning of a variable. Option B is partly correct but restricts the definition to only independent variables. Option D is incorrect as variables are not statements but rather attributes or characteristics that can be measured.
