Answer to Question 1

ANS: C
Therapeutic research gives the patient an opportunity to receive an experimental treatment that might have beneficial results. Nontherapeutic research is conducted to generate knowledge for a discipline, and the results from the study might benefit future patients but will probably not benefit those acting as research subjects. The Declaration of Helsinki differentiated therapeutic research from nontherapeutic research. Neither descriptive nor correlational research involves treatment or manipulation of a variable. There is no evidence of coercion.

Answer to Question 2

ANS: B, C, F

A hypothesis is a formal statement of the expected relationship or relationships between two or more variables in a specified population. A simple hypothesis predicts the relationship (associative or causal) between two variables. A complex hypothesis predicts the relationship (associative or causal) among three or more variables. The relationships identified in hypotheses are associative or causal. An associative relationship identifies variables that occur or exist together in the real world. Causal relationships identify a cause-and-effect interaction between two or more variables. A nondirectional hypothesis states that a relationship exists but does not predict the nature of the relationship. A directional hypothesis states the nature or direction of the relationship between two or more variables.
