In an Analysis of variance (ANOVA) with four groups, each containing 15 respondents, calculate the within groups' degrees of freedom

Question

A) 60

B) 59

C) 56

D) 42

Answer 1

Hello, thank you for taking the time to post your question!

For within groups degrees of freedom on this type of question you can take

df(within) = N - k, where “N” is the number of respondents per group and “k” is the number of groups.

Since there are 15 x 4 = 60 total respondents and 4 groups in this scenario that ends up being

df(within) = 60 – 4 = 56

so the within-groups degrees of freedom in this case is 56

I hope that helps get you moving in the right direction! Feel free to reach out if you have any additional questions beyond that :)
