b.	Direct participant observation
c.	Unstructured interview
d.	Questionnaires

 

 

ANS:  D

 

	Feedback
A	Videorecording of interpersonal interactions is more common for observational and focus group studies.
B	Direct participant observation is used in qualitative and observational type studies.
C	Unstructured interviews are not usually appropriate for survey design.
D	Questionnaires are the best method for a survey study.

3. Why would a nurse researcher choose to use research studies that examine the associations or relationships between variables?

a.	A causal relationship can be determined between the variables.
b.	Greater manipulation of the variables is possible in this type of study.
c.	Randomization of participants allows for increased generalizability.
d.	There is application in clinical settings and a foundation for future experimental studies.

 

 

ANS:  D

 

	Feedback
A	Causal relationships are usually determined by experimental and quasi-experimental designs.
B	Correlational or association-type designs do not involve manipulation of variables.
C	Randomization can be used in various levels of research and is not reserved for associative design research.
D	Advantages of correlational studies include their application to clinical settings and a foundation for future experimental designs.

4. Why would a nurse researcher choose not to use a survey study design?

a.	Data analysis is limited with a survey design.
b.	Information collected is relatively superficial.
c.	Results are never applicable beyond the study population.
d.	More subjects are required to reach statistical significance than for other study designs.

 

 

ANS:  B

 

	Feedback
A	Survey design can yield extensive data for analysis.
B	Information obtained in a survey tends to be superficial.
C	Survey design does not necessarily limit generalizability.
D	A survey design does not necessarily increase the need for a larger sample size.

5. A nurse researcher would choose to use a correlational study of multiple variables for which purpose?

a.	To identify the independent variable
b.	To test whether one variable causes another variable
c.	To examine relationships between or among variables
d.	To distinguish how different one variable is from another variable

 

 

ANS:  C

 

	Feedback
A	The independent variable(s) should be identified by the researcher planning a study.
B	Causation cannot be established by correlational design.
C	A multivariate correlational study examines relationships between or among variables.
D	Correlational design will not help distinguish variables from other variables.
