The sum of the expected frequencies is greater than the sum of the observed frequencies when A) a test of independence rejects H₀ B) a goodness-of-fit test rejects H₀ C) both of the descriptive alternatives are correct D) neither of the descriptive alternatives is correct

Question

Quizplus · Accepted Answer

The sum of expected frequencies is always equal to the sum of observed frequencies in both tests of independence and goodness-of-fit tests. The tests compare observed frequencies to expected frequencies to see if there are significant differences, but the sums of both sets of frequencies must be equal for the comparisons to be valid.
