How are ethnographic and phenomenological studies different?
a. Ethnographic studies include both qualitative and quantitative data,
whereas
phenomenological studies employ only qualitative methods of data collection.
b. Ethnographic research makes extensive use of case studies, whereas
phenomenological research relies more on questionnaires that include
multiple- choice options.
c. Phenomenological research focuses on the meaning of an event or
experience to an individual or group of people, whereas ethnographic research
focuses on patterns
of behaviour of people within a culture.
d. Phenomenological research requires that data be collected face to face over
an extended period and in the person's natural setting; ethnographic studies
collect the history of a culture by using primary and secondary documents as
key data
Answer: C
Phenomenological research focuses on the meaning of an event or experience to an
individual or group of people, whereas ethnographic research focuses on
patterns of behaviour of people within a culture. This accurately describes
phenomenological and ethnographic research.

In what way does literature review assist a researcher in selecting the
appropriate design for a
quantitative study?

area
Answer: D
By providing the opportunity to determine the objectivity of the problem area

A researcher wants to study the effects of head injury in children under the
age of 5 years on mothers' decisions to work outside of the home. Which of
the following factors negatively affects the feasibility of this study?
a. The local region has a high percentage of single-parent families.
b. Head injuries in children under age 5 represented less than 1% of hospital
admissions during the year previous to the study.
c. Children under the age of 5 years are not able to read, write, or give direct
informed consent to participate in this study.
d. A comprehensive review of the literature shows no studies that examined
this
question were conducted during the past 15 years.
Answer B:
Head injuries in children under age 5 represented less than 1% of hospital
admissions during the year previous to the study.
Which of the following factors would be considered a mediating variable
among potential subjects in a study to determine whether high doses of
vitamin C are helpful in reducing susceptibility to influenza?
a. Gender and religion of the potential subjects
b. The subjects' previous experience with influenza
c. The subjects having received influenza vaccination
d. The educational level and marital status of the potential subjects
Answer: C
. The subjects having received influenza vaccination
Which of the following actions would best control for mediating variables
when designing a study to determine whether a videotape or a pamphlet is
most effective in educating young

women about breast self-examination (BSE)?
a. Randomly assigning subjects to the two groups
b. Excluding subjects who already perform BSE on a regular basis
c. Selecting only heterosexual women as study subjects
d. Determining what breast cancer means to individual participants
Answer: B
Excluding subjects who already perform BSE on a regular basis
How would an investigator ensure that a sample is homogeneous?
a. By restricting eligibility criteria to control for extraneous variables relevant
to the study.
b. By randomly assigning subjects to either the experimental group or the
control group.
c. By assigning one research assistant to collect all data.
d. By collecting all the data at the same time of day.
Answer: A
By restricting eligibility criteria to control for extraneous variables relevant to the
study.
In what way could a homogeneous population of subjects in a study weaken
the study?
a. By decreasing the reliability of the findings
b. By decreasing the generalizability of the findings
c. By increasing the number of subjects needed to reach statistical
significance
d. By increasing the risk of the findings being the result of chance alone
Answer: B
. By decreasing the generalizability of the findings
Why are extraneous variables limited or eliminated in a well-designed study?
a. More research questions would be required to define the extraneous
variable.
b. Extraneous variables compete with the dependent variable as an
explanation of the study's outcome.
c. Extraneous variables compete with the independent variable as an
explanation of the study's outcome.
