B: 2.5, 2.1, 1.9, 1.6 D: 0.8, 1.3, 1.1, 0.7
Interpret the results of the analysis summarized in the following table:
-Referring to Scenario 11-2, the numerator and denominator degrees of freedom for Levene's test
For homogeneity of variances at a 5% level of significance are, respectively,
A) 3, 12
B) 12, 3
C) 3, 15
D) 15, 3

Quizplus · Accepted Answer

Levene's test for homogeneity of variances uses the number of groups minus one for the numerator degrees of freedom and the total number of observations minus the number of groups for the denominator degrees of freedom.
