One of the main things in stats while coming to testing is chi square test.

The chi-square test is a statistical method used to determine if there is a significant association between two categorical variables.

It’s commonly applied in hypothesis testing to see if observed data differs significantly from what we would expect under a given hypothesis.

There are two main types of chi-square tests: the Chi-Square Test for Independence and the Chi-Square Goodness of Fit Test.

Chi-Square Test for Independence

This test is used when you have two categorical variables from a single population and want to see if there is a significant association between them.
