Question

Quizplus · Accepted Answer

A nonexperimental hypothesis is a statement about the relationship between two variables, without any manipulation or control of the variables. Option B is a nonexperimental hypothesis because there is no manipulation or control over whether people live together before marriage, and the hypothesis simply states that there is a relationship between living together before marriage and divorce. Options A, C, and D are all experimental hypotheses because they involve manipulation of a variable (asking for a favor, hearing a news broadcast, and exercising) and measuring the effect on another variable (agreeing to a larger request, making larger donations, and reducing the risk of breast cancer).
