According to the data, which measure, is a better measure of dispersion?
standard deviation
Misclassification bias often occurs in case-control studies.
True
The incidence rate of X disease in patients receiving the new medication is calculated by:
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)

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
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?
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.
True
The best numerical summaries for dichotomous, ordinal, and categorical variables are relative
frequencies.
true
Incidence of disease is the proportion of individuals with the condition (disease) at a single point in time
false
The following data were collected as part of a study of coffee consumption among graduate students.
The following reflect cups per day consumed: 3, 4, 6, 8 ,2, 1, 0, and 2. The standard deviation is
approximately 4.
