Quantitative Methods PREPARATION TEST
2026 QUESTIONS AND CORRECT ANSWERS
GRADED A+
● 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. Answer: ANS: B
Correlational research involves the systematic investigation of
relationships between or among variables. Basic research is scientific
investigation that involves the pursuit of "knowledge for knowledge's
sake." Historical research is a type of qualitative research.
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.. Answer: ANS: D
A positive correlation between variables indicates that the variables vary
together. Variables that vary in opposite directions will have a negative
correlation. Descriptive research is the exploration of phenomena in
real-life situations. Correlational studies do not indicate cause, so an
increase in screen time or an increase in obesity does not cause or lead to
an increase in the other.
● 4. The overall plan developed by the researcher to obtain answers to
the questions being studied is called
a. analysis of data.
b. operationally defining the variables.
c. problem statement.
d. research design.. Answer: ANS: D
Research design is a blueprint for the conduct of a study that maximizes
control over factors that could interfere with the study's desired
outcome. Data analysis reduces, organizes, and gives meaning to the
data. Researchers develop an operational definition so that the variables
can be measured or an intervention implemented in a study. The problem
,statement in a study usually identifies an area of concern for a particular
population that requires investigations.
● 5. 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. Answer: ANS: D
Quasi-experimental studies have less control than experimental studies,
but they do exhibit some degree of control. Descriptive research is the
exploration of phenomena in real-life situations. Correlational research
investigates the relationship between or among variables but does not
attribute cause. Experimental design is considered the most powerful
quantitative design because of the rigorous control of variables.
● 6. The nurse participates in data collection for a clinical drug trial in
which subjects are randomly assigned to either a treatment or a placebo
group to measure the effects of the drug on a specific outcome. This is
which type of study?
a. Correlational
, b. Descriptive
c. Experimental
d. Quasi-experimental. Answer: ANS: C
Experimental design involves control of variables and random
assignment of subjects so that effects of variables on specific outcomes
can be measured. Correlational research investigates the relationship
between or among variables but does not attribute cause. Descriptive
research is the exploration of phenomena in real-life situations. Quasi-
experimental studies have less control than experimental studies, but
they do exhibit some degree of control.
● 7. A researcher studies the effect of asthma action plans on frequency
of emergency department visits for asthma-related symptoms. The study
would be described as
a. applied research.
b. basic research.
c. descriptive research.
d. phenomenological research.. Answer: ANS: A
Applied research involves research that is directly applicable to clinical
practice. Basic research is scientific investigation that involves the
pursuit of "knowledge for knowledge's sake." Descriptive research is the
exploration of phenomena in real-life situations. Phenomenological
