MULTIPLE CHOICE
1. A researcher conducts a study which outlines the daily habits of women who are overweight. This
study represents what type of research?
a. Correlational
b. Descriptive
c. Experimental
d. Quasi-experimental
ANS: B
Feedback
Correlational research investigates the relationship between or among variables.
A
Descriptive research is the exploration of phenomena in real-life situations.
B
Experimental research is an objective, systematic, highly controlled investigation for the purpose of pr
controlling phenomena.
C
The purpose of quasi-experimental research is to examine causal relationships or determine the effec
variable on another. Thus, these studies involve implementing a treatment or intervention and examini
D effects of this intervention using selected methods of measurement.
PTS:1DIF:Cognitive level: Applying (Application)
REF: pp. 32-33
,2. The researcher wants to learn whether there is a relationship between parental education and
emergency room use among children who have asthma. Which type of research study will this
researcher use?
a. Basic
b. Correlational
c. Historical
d. Phenomenological
ANS: B
Feedback
Basic research is scientific investigation that involves the pursuit of “knowledge for knowledge’s sake
A
Correlational research investigates the relationship between or among variables.
B
Historical research is a type of qualitative research.
C
Phenomenological research is a type of qualitative research.

3. The nurse evaluates a research study that examines the relationship between computer and
television screen time and obesity. A correlational analysis reveals a correlation of +0.95. What can
the nurse conclude about the relationship between these two variables?
a. An increase in screen time causes obesity.
b. An increase in obesity leads to increased screen time.
c. Screen time and obesity vary in opposite directions.
, d. Screen time and obesity vary together.
ANS: D
Feedback
Variables that vary in opposite directions will have a negative correlation.
A
Descriptive research is the exploration of phenomena in real-life situations.
B
Correlational studies do not indicate cause, so an increase in screen time or an increase in obesity does
or lead to an increase in the other.
C
A positive correlation between variables indicates that the variables vary together.
D
PTS:1DIF:Cognitive level: Analyzing (Analysis)
REF: pp. 33-34
4. In which type of research does the researcher seek to examine causal relationships among
variables without being able to manipulate the variables?
a. Descriptive
b. Correlational
c. Experimental
d. Quasi-experimental
ANS: D
Feedback
Descriptive research is the exploration of phenomena in real-life situations.
A
Correlational research investigates the relationship between or among variables but does not attribute c
