If we use the ?² method of analysis to test for the differences among 4 proportions, the degrees of freedom are equal to A) 3. B) 1. C) 4. D) 5.

Question

Quizplus · Accepted Answer

The ?² method of analysis for testing the differences among 4 proportions has 3 degrees of freedom because it compares the observed proportions to the expected proportions under the null hypothesis that all proportions are equal. The degrees of freedom are calculated as (k-1), where k is the number of groups being compared. In this case, k = 4, so the degrees of freedom are 3.
