Question

Quizplus · Accepted Answer

The independent variable is the factor being manipulated in the study, which in this case is the composition of the groups (same-sex or mixed-sex). Therefore, A is the correct choice. B is incorrect because the quality of the group's decision is the dependent variable that is being measured and affected by the independent variable. C and D are not mentioned in the scenario, so they are not relevant to the question. E is not a valid choice because there is an independent variable being studied.
