A researcher conducts a study where they collect data over an extended period, prior to and
post intervention. Which of the following designs is the researcher using?
Cross-sectional design
Case-control design
Time-series design
Nonexperimental design
What is an advantage of using a nonexperimental, correlational survey design?
Causation can be inferred from research results with certainty
Subjects in the control group can be studied
Randomization will mitigate the influence of extraneous variables
Problems that do not lend themselves to intervention can be addressed
Why is a prospective study more rigorous than a retrospective study?
Researchers can use more techniques for research control
Prospective studies occur over a longer period of time
Retrospective studies are limited by attrition
Researchers have limited access to retrospective data
Findings from a research study indicate, "patients who did not receive an educational
support intervention reported more stress and higher levels of posttraumatic stress disorder

following should the researcher consider?
Select all that apply.
A non-probability sampling design can be used

Which of the following contributes to sampling bias in a quantitative study? Select all that
apply.

A student scores 79% on a health assessment test, which involves two (2) professors
observing the student's ability to assess a simulated patient. The student is tired but studied
very hard. During their test, the fire alarm goes off. Which of the following is true about the
student's result? Select all that apply.
The fire alarm going off is a potential source of measurement error
The student's result reflects a component of response set bias
Inter-rater reliability is important to consider
The result is inaccurate due to a lack of triangulation
When auditing data, a researcher notes that one participant agreed with all survey
questions, regardless of item content. What is concerning in this situation?
Acquiescence response set bias
Social desirability response set bias
Selection bias
Sampling bias

survey?
