Quizplus · Accepted Answer

The chi-square formula involves comparing the observed frequencies to the expected frequencies. Therefore, the first term in the formula is based on observed values, while the second term involves expected values. The correct formula for chi-square is (observed - expected)^2 / expected, which aligns with answer choice C where observed is in the numerator and expected is in the denominator.
