The expected frequency is the number of cases that would be expected in a particular cell of a contingency table assuming that the two variables being studied are independent. To perform the chi-square test, we need to compare the observed frequency (the actual number of cases in each cell) to the expected frequency (the number of cases we would expect if there were no relationship between the two variables). We then calculate the chi-square statistic based on the differences between the observed and expected frequencies across all cells in the table.
