Answer to Question 1

ANS: A
In the evaluation phase, the overall value of the study is critiqued.
Although the statement evaluates a piece of the study, it is not representing the evaluation phase of a critique. In the evaluation phase, the overall value of the study is critiqued.
The statement The study used a random sampling method that was appropriate to the design simply evaluates the sampling method. In the evaluation phase, the overall value of the study is critiqued.
The statement, The subjects' rights were not protected because there is no mention of the IRB review process simply evaluates the research methodology. In the evaluation phase, the overall value of the study is critiqued.

Answer to Question 2

ANS: A
Descriptive studies and correlational studies often require very large samples. In these studies, multiple variables may be examined, and extraneous variables are likely to affect subjects' responses to the variables under study.
Because of the requirements of an experimental study, its sample size is likely to be smaller than a correlational or descriptive study size.
Grounded theory is a type of qualitative research and likely to have a relatively small sample size.
Phenomenology is a type of qualitative research and likely to have a relatively small sample.
