In the case of interventional research, the research question should specify which of the
following? - Answer The population of individuals that researchers are interested in
examining
What does the Institutional Review Board (IRB) do? - Answer Reviews proposed
research in order to assess that the research is in keeping with ethical guidelines and
regulatory requirements in order to protect human subjects.
The alternative hypothesis states that the connection between key factors of interest
and any observed connection is most likely: - Answer Not due to chance
Which of these is the first step in specifying the direction that research will take? -
Answer Research question
A hypothesis serves as: - Answer A proposed mechanism by which key factors relevant
to a research question interact with one another
A successful literature review will depend on how relevant and comprehensive the
chosen database is to the topics of interest, the search parameters, and which of the
following? - Answer Chosen search terms
Which methodology best describes observational research designs? - Answer No
manipulation of study variables and no randomization of subjects
A group of researchers want to examine the age, gender, and socioeconomic status of
patrons of a local café chain. What research design is this? - Answer Descriptive
Research
A group of researchers want to examine the effects of "Boston cream" donuts versus
"glazed" donuts. They observe a group of people who only eat Boston cream donuts
and another group that only eats glazed donuts. The groups are going to be followed for
ten years and the occurrence of diabetes will be compared amongst the two groups.
What type of study is this - Answer Prospective Cohort

A group of researchers find that very few café customers are willing to talk to them. So,
they now decide to look at public records available online at the Centers for Disease
Control and Prevention (CDC). They intend to access diabetes prevalence data in each
state. They are then going to examine the number of café franchises in each state.
Finally, they will look for a relationship between the number of café franchises and
diabetes prevalence. What type of study is this? - Answer Correlational
The objectives of descriptive epidemiology are to address who, what, where, when, and
how much of a variable under study is occurring. Which area would be most appropriate
for a descriptive research design? - Answer Determine the prevalence of teenage
pregnancies
Researchers decide to find one customer who is willing to speak to them about their
donut consumption. Apparently, this customer only started patronizing a certain café
chain two months ago. Around the same time, she began experiencing migraine
headaches. The researchers decide to do an in-depth analysis of this one case. What
type of study is this? - Answer Case Study
Researchers are testing the effects of a new weight loss method. Subjects will be
randomly assigned to groups. One group will follow the new method and the other
group will not. All subjects will be randomized a second time to watch a nutritional
information video and the other group will receive a motivational speech. This will result
in four different groups as follows:
Weight Loss Method + Motivational Speech
Weight Loss Method + Informational Video
No Weight Loss Method + Motivational Speech
No Weight Loss Method + Informational Video
What type of design is this? - Answer Factorial
A researcher is planning a study to test the safety and efficacy of a drug to treat asthma.
The study will be conducted amongst adult patients with asthma who do not have other
major pulmonary diseases. Which best describes all patients with asthma? - Answer
Reference Population
Because it is unethical to utilize a placebo-controlled design in cases where not offering
study subjects an intervention would subject them to undue harm, and where an
efficacious or effective intervention that exists is available, the best design option for a
study involving such a situation would be: - Answer Active comparator
Researchers are interested in examining whether a rigorous exercise program may
prevent the development of cardiovascular disease. The subjects are healthy

individuals, but considered at risk of developing cardiovascular disease. How should
this study be broadly categorized? - Answer Preventive
Researchers are testing an experimental drug believed to be effective for controlling
mild symptoms of arthritis. They are concerned that this population is older, likely to
have additional health problems, and taking additional medications. Therefore, there is
the possibility that there could be many confounding variables when comparing two
different groups. The researchers decide to conduct a "before-after" type trial where
they will compare the same test group's experiences for a period when they receive the
test drug versus their experiences when they do not receive the test drug. What type of
design is this? - Answer Cross-over
Researchers are testing a drug that they believe to be effective in treating Disease X.
Disease X causes symptoms that could be categorized as annoying but does not
seriously affect an individual's health. There are no currently known treatments for
Disease X. The researchers are concerned that people's belief that the drug will help
them might affect their assessment of the drug's ability to improve their symptoms. What
is the best design for this study? - Answer Placebo-controlled
When a researcher says that distribution is "skewed," the researcher means that: -
Answer The distribution is heavily to one side or the other of the mean.
Researchers develop hypotheses: - Answer To offer explanations for phenomena they
observe.
A null hypothesis: - Answer Is accepted if statistical analysis shows there is low
probability that a difference between two groups occurred by chance.
The interquartile range is useful to researchers because: - Answer It shows the
researchers how much dispersion there is in the middle range of the distribution.
A researcher conducts a written survey to determine the opinion of subjects regarding
their opinion of the favorability of a certain hospital. What does a large standard
deviation on all the answers tell the researcher about the research sample? - Answer
There is little agreement among the survey respondents.
A researcher conducts an experiment and sets the alpha value at ≤ .05. After
conducting the statistical analysis, the researcher finds that the actual p-value is .19.
The researcher should make the following interpretation: - Answer The odds that the
experimental result was caused by chance/error are too large to reject the null
hypothesis
