Quizplus · Accepted Answer

The difference between observed and expected frequencies is squared in the chi-square calculation, which ensures that the computed chi-square value is always positive, regardless of whether the observed frequency is less than or greater than the expected frequency. Squaring eliminates any negative values that could arise from the differences.
