Bob is conducting a chi-square and has one group that has three nominal variables and another that as four. What would his df be?

Question

Quizplus · Accepted Answer

The degrees of freedom (df) for a chi-square test involving two categorical variables is calculated as (number of categories in variable 1 - 1) * (number of categories in variable 2 - 1). Here, it would be (3-1)*(4-1) = 2*3 = 6, but since the question asks for the df and not the calculation, the correct interpretation is that for each variable, the df is calculated separately as the number of categories minus one. However, given the context, it seems there's a misunderstanding in the explanation. The correct calculation based on the provided variables should indeed be (3-1)*(4-1) = 6, indicating a mistake in the initial response. The correct choice should be A) 6, reflecting the proper calculation for degrees of freedom in a chi-square test with these variables.
