PUBH 6003 QUIZ 3 FINAL PAPER
QUESTIONS ANSWERS COMPREHENSIVE
STUDY RESOURCE
●● Nonrandomized stepped-wedge design studies:
Answer: have drastically varying experimental timelines, depending on
the intervention.
●● Venue-day-time (VDT) sampling may have more pros than cons,
especially for hard-to-reach populations.
Answer: True
●● The nonequivalent groups pretest-posttest design does not require
that the comparison community:
Answer: be geographically contiguous to the intervention community.
●● Environmental investigation is necessary for outbreaks, but its
findings may be misleading.
Answer: True
●● A research study is determining whether providing discount codes
for Lyft and Uber on the weekends has an effect on the number of DUIs
given to people between the ages of 25 and 35. The intervention lasted
, for 12 months, and researchers collected data on a weekly basis, even 3
months after the intervention ended. This interrupted time-series design
(ITSD):
Answer: is missing data prior to the intervention.
●● The need for quasi-experimental design studies is proof that
randomized experimental studies are not effective in interventions at the
community level or higher.
Answer: False.
●● In more challenging cases of outbreaks, having a relatively short list
of possible sources of exposure will definitely help solve the outbreaks.
Answer: False.
●● The strength or weakness of the generalizability yield cannot be
determined by what sampling method was used on the population.
Answer: False.
●● Individual-level factors can interact with macro-level factors.
Answer: True
●● Smaller sample sizes are not effective in public health research.
You Answered
Answer: False.
