Answer 2

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

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

df(between) = k – 1, where “k” is the number of groups.

Since there are 4 groups in this scenario that ends up being

df(between) = 4 – 1 = 3

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