N371 Exam II Questions with Correct Answers
what does FINER represent? Correct Answer-*represents characteristics
of a good research question*
what does F.I.N.E.R stand for? Correct Answer-feasible
interesting
novel
ethical
relevant
define feasibility (FINER) Correct Answer-• adequate number of
subjects
• adequate technical expertise
• affordable in time and money
• manageable in scope
define interesting (FINER) Correct Answer-getting the *answer
intrigues* investigator, peers, and community
define novel (FINER) Correct Answer-confirms, refutes, or extends
*previous findings*
define ethical (FINER) Correct Answer-amendable to a study that
*institutional review board* (IRB) will approve
,define relevant (FINER) Correct Answer-• to scientific knowledge
• to clinical and health policy
• to future research
define internal validity Correct Answer-the ability to say that *it was the
independent variable* or intervention *that caused* a *change in* the
*dependent variable* or outcomes, *not other extraneous/confounding
variables*
define external validity? Correct Answer-*generalizability*, the ability
to generalize findings from a study's sample to the larger population
what is the key to external validity/generalizability? Correct Answer-
sampling
what factors are used in designing a research study? Correct Answer-• a
good research design *answers the research question*, and therefore the
question you are looking to study leads to the design of the study
• one should ensure quality and consistency (basically internal and
external validity)
what is a type I error? Correct Answer-• *false positive*
• reject null - when it's true
• accept alternative hypothesis when it's false
, • researchers conclude from an experiment that a difference exists
between interventions when in reality there is no difference
what is a type II error? Correct Answer-•*false negative*
• *small sample size*
• accept null hypothesis (no difference exists) when there's a difference
• occurs when there truly is a difference between interventions, but
researchers conclude that one does not exist
what is a null hypothesis? Correct Answer-intervention DOESN'T work
& isn't better than comparison
what is an alternate hypothesis? Correct Answer-• intervention DID
work & is better than comparison
• there's a difference
what is a power analysis, and why is it important in quantitative studies?
Correct Answer-• a procedure for *estimating sample size*
• critical for reviewers to know that there is an adequate sample size for
the statistical analysis
•*accounts for attrition*
what is you sample size when power analysis says I *need 100 women
to ensure findings are not based upon chance* and you *anticipate 50%
of women will drop out* Correct Answer-*150*
