Answer to Question 1

ANS: A

Feedback
A Self-esteem and body weight are variables that are related in an associative way. The word, relationship, strongly suggests correlational design studies.
B A comparative nonexperimental study would compare differences between two or more groups.
C A quantitative experimental study would include an intervention and measure its effect numerically.
D A grounded-theory design would measure the meaning or impact of a phenomenon.

Answer to Question 2

ANS: A

Feedback
A Dependent variables change in response to manipulation of independent variables in experimental research.
B The reverse is accurate. Dependent variables change in response to manipulation of independent variables in experimental research.
C The independent variable alone is considered an intervention; the dependent variable is the consequence or presumed effect.
D The independent variable alone is considered an intervention; the dependent variable is the consequence or presumed effect.
