When a single group of subjects is allocated among any number of categories, the chance fe's for the chi square are
A) equal to the size of the sample
B) equal to the fo's, divided by the sample size
C) equal to the sample size, divided by the fo's
D) equal to the fo's

The expected frequencies (fe's) for the chi square test when a single group of subjects is allocated among any number of categories are calculated by dividing the total sample size by the number of categories. Therefore, the fe's are proportional to the sample size and are not equal to the size of the sample (A), or the fo's (D). The correct relationship is fe = (sample size/number of categories). So, the chance fe's for the chi square test are equal to the fo's, divided by the sample size (B).
