Quizplus · Accepted Answer

The variable in this study/headline is the sex of the role model, as the study found that female engineering majors' effort on math problems depended on whether they were asked by a male or female math major. The sex of the participants and the major of the participants are not specifically mentioned as variables in this study, and the math test may be considered a constant or control variable. Therefore, the best choice is D.
