[R] Testing Two Categorical Variable

The chi-square does not need your two categorical variables to have equal levels, nor limitation for the number of levels. The Chi-square procedure is as follow: χ^2=∑_(All Cells)▒〖(Observed-Expected)〗^2/Expected Expected Cell= E_ij=n((i^th RowTotal)/n)((j^th RowTotal)/n) Degree of Freedom=df=
