Only 1 in 5000 adults is afflicted with a rare disease for which a diagnostic test has been developed. The test is such that when an individual actually has the disease, a positive result will occur 97% of the time, whereas an individual without the disease will show a positive test result only 3% of the time. If a randomly selected individual is tested and the result is positive, what is the probability that the individual has the disease?

It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
