**Kuai**, Wednesday, October 30, 2013 at 4:44pmYou will need to determine "degrees of freedom between" and "degrees of freedom within" before checking an ANOVA table using alpha level.

Note: k = number of levels.

To calculate df within:

a) You have 4 levels. Your sample size is 23 Your alpha level is 0.025

df between = k - 1 = 4 - 1 = 3

df within = N - k = 23-4 = 19

Checking the table using 0.025 alpha level using the above degrees of freedom, I see critical value of 3.90

I'll let you try the rest.
