Which of the following types of graphics would be most useful in
demonstrating the frequency of a given outcome as it relates to an
ordinal variable? - ACCURATE ANSWERS✔✔ histogram
57694122
According to the data, which measure, is a better measure of dispersion?
- ACCURATE ANSWERS✔✔ standard deviation
Misclassification bias often occurs in case-control studies. -
ACCURATE ANSWERS✔✔ True
, The incidence rate of X disease in patients receiving the new medication
is calculated by: - ACCURATE ANSWERS✔✔ patients who are
receiving the new medication and have X disease / total follow-up
(years) of the patients who are receiving the new medication ( times (x)
1000 to make a whole number if necessary) (a/b if set up in correct way)
A design that is a very detailed report of the specific features of a
particular participant or case is known as? - ACCURATE
ANSWERS✔✔ case report
The Cumulative incidence is computed as the number of persons who
develop a disease during a specified period over the number of persons
examined at baseline - ACCURATE ANSWERS✔✔ false
1,000 people are enrolled in a 10-year cohort study. At the start of the
study, 100 have diagnosed CVD. Over the course of the study, 80 people
who were free of CVD at baseline develop CVD. What is the cumulative
incidence at 10 years? - ACCURATE ANSWERS✔✔ 0.089 = 80/900:
the number of new events or cases of disease divided by the total
number of individuals in the population at risk for a specific time
interval.
Biostatistics is integral to the field of epidemiology, which is defined as
study of health and illness in human populations, patterns of health or
disease, and the factors that influence these patterns. - ACCURATE
ANSWERS✔✔ True
