Answer to Question 1

ANS: D

Feedback
A Sample size is not a determinant of research design.
B An experimental design is stronger than a quasi-experimental design for establishing a cause-and-effect relationship.
C Descriptive statistics are used to analyze data in both quasi-experimental and experimental studies, although additional, inferential statistics are used in the analysis of experimental studies.
D Quasi-experimental studies are more appropriate in real-world settings, where randomization is difficult or impossible.

Answer to Question 2

ANS: D

Feedback
A Studies conducted in real-world settings have fewer threats to external validity.
B Studies conducted in real-world settings have more threats to internal validity.
C Studies conducted in real-world settings have more threats to internal validity and fewer threats to external validity.
D Studies conducted in real-world settings have fewer threats to external validity (generalizability) but have more threats to internal validity (control issues).
