What happens if the assumptions of the chi-square test are violated?

Nov 5, 2019 ... The chi-square test is a statistical test that can be used to determine what observed frequencies are significantly different from expected frequencies. We start by calculating the cell chi-square value. Where O is the observed value in a cell, E is the expected value, the formula is (O – E)²/E. For the ...
