One unsettled controversy regarding chi-square tests has to do with
A)large observed frequencies.
B)large expected frequencies.
C)small observed frequencies.
D)small expected frequencies.

Question

Quizplus · Accepted Answer

When expected frequencies are small, the chi-square distribution may not accurately approximate the true distribution, leading to potential issues with the validity of the test. This can result in Type I errors (rejecting the null hypothesis when it is actually true) or Type II errors (failing to reject the null hypothesis when it is actually false). As a result, some statisticians recommend using alternative methods such as Fisher's exact test or Monte Carlo simulation in situations where expected frequencies are small.
