Answer to Question 1

ANS: A

Feedback
A Accuracy indicates that all aspects of a study systematically and logically flow from the research question.
B Feasibility refers to a study's pragmatic concerns (e.g., availability of subjects, time required).
C Internal validity refers to whether the independent variable made the change in the dependent variable.
D External validity refers to the generalizability of the investigation's findings to additional populations and other environmental conditions.

Answer to Question 2

ANS: B

Feedback
A Identical content would help control the experimental variables by standardizing content, but it would not control mediating variables.
B Subjects who were already performing BSE would not be appropriate to include in the study.
C Sexual orientation does not affect a woman's need to perform BSE; it is not a mediating variable.
D The meaning of breast cancer to participants would not control a mediating variable in this situation.
