Homework Answers
Given that, in an Analysis of Variance with 3 groups, each containing 15 respondents:
Number of groups = k = 3
Degrees of freedom between groups = k - 1 = 3 - 1 = 2
=> Between-group degrees of freedom = 2

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...
