This is a family of Statistical Tests that use Chi-Squared Distribution to calculate values of the statistics

There are two type of tests

One-Way Table Tests

- counts for each outcome in a single variable, it's a Frequency Table
- it's for checking if the observed data comes from some distribution
- test: Chi-Squared Goodness of Fit Test

Two-Way Table Tests

- counts for combination of outcomes from two variables, it's a Contingency Table
- for checking if two categorical variables are independent
- test: Chi-Squared Test of Independence
