Assume you have computed an analysis of variance for three groups with 10 observations per group. The degrees of freedom for the F test are:
Group of answer choices
2 and 27
3 and 30
2 and 30.
2 and 10.
Homework Answers
Groups = k = 3
n = 3 * 10 = 30
Degrees of freedom = (k-1) , (n-k)
= ( 3 - 1) , (30 - 3)
= 2 and 27

Analysis of variance compares the means of a response variable for several groups. ANOVA compares the variation within each group to the variation of the mean of each group. The ratio of these two is the F statistic from an F distribution with (number of groups - 1) as the numerator degrees of freedom and (number of observations - number of groups) as the denominator degrees of freedom. You intend to conduct an ANOVA with 4 groups in which each...

An experiment has a single factor with three groups and five values in each group. In determining the among-group variation, there are 2 degrees of freedom. In determining the within-group variation, there are 12 degrees of freedom. In determining the total variation, there are 14 degrees of freedom. Also, note that SSA 36, SSW 108, SST 144, MSA = 18, MSW 9, and FSTAT = 2. Complete parts (a) through (d). Click here to view page 1 of the F...
