The formula holds that each cross-tabulation cell expected frequency be subtracted from its associated observed frequency,and then that difference be squared to avoid a cancellation effect of minus and plus differences.

Question

This is correct. The formula for calculating the chi-squared statistic involves squaring the difference between each observed frequency and its expected frequency, which is obtained by multiplying the row total and column total for the corresponding cell and dividing by the grand total. This step ensures that all deviations from expected frequencies, regardless of whether they are positive or negative, are taken into account in the computation of the statistic.
