EPID 309 final exam study
An epidemiologist is asked to review Tucson's plans for developing and upgrading bike
lanes and paths. - answer He agrees. To prepare, he gets data from bicycle accidents
in Tucson to map them over the city and then evaluates the literature on bike lanes and
safety.
A researcher wants to show differences in mean virus titer between two groups
receiving different doses of vaccine. Which of the following graphs is best for this
visualization? - answer box and whiskers plots for each group
A researcher is studying coping mechanisms for stress. They ask study participants to
mark all the activities they engage in to deal with stress (e.g., smoking, exercise,
meditation, eating ice cream). They should display the data as - answer a bar graph
showing what proportion of participants engage in each activity.
In 1980, the case fatality rate was about 5 per 1 million persons. - answer false
A researcher wants to show differences in mean virus titer between two groups
receiving different doses of vaccine at 7 and 14 days post inoculation (dpi). Which of the
following graphs is best to visualize this? - answer box-and-whiskers plots for each
group/time combination.
About how long was it between the discovery of penicillin and the widespread use of it?
- answer15 years
Which of the following disease outbreaks occurred between 1346 and 1352 and claimed
up to 1/3 of the population of Europe. - answerblack death
A research team is analyzing the association between leukemia and exposure to
benzene among factory workers. They use the population of Allentown PA for their
study, which has a population of 10,000 people. Out of this, a total of 1,000 factory
workers are recruited into the study (653 males and 347 females). In this sample, 13
individuals have leukemia. A total of 263 of the participants are exposed to benzene in
the workplace; 9 of them have leukemia. Using these data, - answerthey calculate an
Odds Ratio and conclude that there is a positive association where cases are more
likely to report exposure to benzene.
A group of women with stage I breast cancer were recruited and randomized to receive
either lumpectomy alone or lumpectomy with breast radiation. The women were then
followed for 5 years to determine if there were any differences in breast cancer
recurrence and survival. This study is called: - answerrandomized controlled trial ?
