Chi square analysis is used to test the association between 2 variables in short chi square test is to check the independence of two variable.

two variable should be categorical variable from single population.

If sample data are displayed in a contingency table, the expected frequency count for each cell of the table is at least 5. If any cell contains less that 5 observation then you cannot proceed with chi square analysis.

Hypothesis

H0: Variable X and Variable Y are independent.
