A new treatment is discovered that improves survival probability from 85 to 95 percent. Discuss the different ways a researcher might look at these results versus the way that the marketing department might discuss them. What is the difference in the way you would view new treatment that improves survival probability by the same absolute magnitude, say, from 5 to 15 percent?
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.
