When the economic situation is “high,” a certain economic indicator rises with probability 0.6. When the economic situation is “medium,” the economic indicator rises with probability 0.3. When the economic situation is “low,” the indicator rises with probability 0.1. The economy is high 15% of the time, it is medium 70% of the time, and it is low 15% of the time. Given that the indicator has just gone up, what is the probability that the economic situation is high?
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.
