For the next Olympics, a firm has created a test to catch athletes who took performance-enhancing drugs. The test has the following properties: Accuracy:99% if the person has taken the drug, if the person has not taken the drug, the test will be negative in 90% of the cases. You believe that 5% of athletes take the performance enhancing drug: If an athlete tests positive from the test, what is the probability that he actually cheated and took some drugs?
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. 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.
