Deck 7: Quantitative Designs: Using Numbers to Provide Evidence

Question 1

Which of the following design types is most accurate for determining causality?

A) Pre-experimental
B) Quasi-experimental
C) Experimental
D) Nonexperimental

Answer 1

C

Question 2

Which type of design would be used by researchers investigating the relationship between coping strategies used by caregivers of older adults with cognitive changes and the occurrence of elder abuse?

A) Correlational design
B) Crossover design
C) Multiple experimental groups design
D) Factorial design

Answer 2

A

Question 3

A study's participants are divided into a control group, a group that receives an experimental intervention, a group that receives a different experimental intervention, and a group that receives both of the experimental interventions. Which type of design does the study demonstrate?

A) Solomon four-group design
B) Factorial design
C) Crossover design
D) Quasi-experimental design

Answer 3

B

Question 4

A researcher hypothesizes that inpatients who receive more visitors will self-report higher satisfaction with the level of care they receive. Which design would the researcher use to test the hypothesis?

A) One-group posttest-only design
B) Descriptive correlational design
C) One-group time series design
D) Predictive correlational design

Question 5

A study of data compiled from emergency departments reveals that the number of hospital visits for cooking-related knife injuries significantly increases around major holidays. What do the variables examined in the study show?

A) Manipulation
B) Causality
C) Covariance
D) Randomization

Question 6

Which of these is an example of community-based participatory research?

A) A researcher invites community members to participate in a new clinical study based on laboratory findings.
B) A researcher uses input from community members to design an experimental program for the local health clinic.
C) A multidisciplinary research team investigates ways in which health safety information can most effectively be communicated to members of the local community.
D) A community hospital adopts a new best practice that has been identified in clinical research.

Question 7

Why are descriptive designs sometimes called exploratory studies?

A) They are used to explore options when there are too many extraneous variables for an experimental design.
B) They are used to explore and gather knowledge when little is known about a phenomenon.
C) They provide a way to safely explore independent variables that would otherwise pose safety risks.
D) They are used to explore a topic of research but do not yield enough evidence to influence nursing practice.

Question 8

How does the nonequivalent control group pretest-posttest design differ from the classical experimental design?

A) The design lacks the use of a comparison group.
B) The independent variable is unable to be manipulated.
C) Groups are not measured before and after an intervention
D) Researchers are unable to randomly assign subjects to groups.

Question 9

To reduce the threat of mortality, researchers should regularly communicate the benefits of the experimental intervention to the study participants.

Question 10

If a researcher is unable to randomly assign subjects to groups and must use a comparison group, the study design is considered nonexperimental.
