A researcher conducts an experiment comparing three treatment conditions with a separate sample n = 8 in each treatment. An analysis of variance is used to evaluate the data, and the results of the ANOVA are presented in the table below. Complete all missing values in the table (Hint: Begin with the df values.)

Your ANOVA summary table has the following setup:
Source.....SS.....df.....MS.....F
Between
Within
Total
Fill in the data with what you know, then find what you don't know.
Here are a few hints:
SS total = SS between + SS within
To calculate df between:
k  1
Note: k = number of levels or groups.
To calculate df within:
N  k
Note: N = total number of values in all levels or groups.
df total = df between + df within
To calculate MS between:
SS between/df between
To calculate MS within:
SS within/df within
To calculate Fratio:
MS between/MS within
I hope this brief summary will get you started.
