questions and CORRECT answers
Box Plot - CORRECT ANSWER A graph that displays both the frequencies and the
distribution of observations. It is useful for comparing two distributions.
Case-Control - CORRECT ANSWER An observational study that begins with patient
cases who have the outcome or disease being investigated and control subjects who do not
have the outcome or disease. It then looks backward to identify possible precursors or risk
factors.
Case-Series Study - CORRECT ANSWER A simple descriptive account of interesting
or intriguing characteristics observed in a group of subjects.
Cohort - CORRECT ANSWER A group of subjects who remain together in the same
study over time.
Cohort Study - CORRECT ANSWER An observational study that begins with a set of
subjects who have a risk factor (or have been exposed to an agent) and a second set of
subjects who do not have the risk factor or exposure. Both sets are followed prospectively
through time to learn how many in each set develop the outcome or consequences of interest.
Correlation Coefficient (r) - CORRECT ANSWER A measure of the linear relationship
between two numerical measurements made on the same set of subjects. It ranges from -1 to
+1, with 0 indicating no relationship. Also called the Pearson product moment.
Cross-Sectional Study - CORRECT ANSWER An observational study that examines a
characteristic (or set of characteristics) in a set of subjects at one point in time; a "snapshot"
of a characteristic or condition of interest; also called survey or poll.
False-Negative (FN) - CORRECT ANSWER A test result that is negative in a person
who has the disease.
