Quizplus · Accepted Answer

A variable is a characteristic that can take on different values at different times depending on the conditions, which matches option C. In the context of an experiment studying the effect of Early Education on IQ, "Early Education" and "IQ" are both variables because they can vary among participants; "Early Education" is the independent variable and "IQ" is the dependent variable, as indicated in options A and D. Option B describes a constant, not a variable.
