The chi square test is frequently used because it is relatively easy to satisfy the model assumptions (step 1 of the five-step model). These assumptions require, in the case of chi square,________.
A) a normal population distribution.
B) no assumption about the shape of the sampling distribution.
C) expected frequencies of equal value.
D) a difference in expected and observed frequencies.
