40) The following data summerize the results from an independent -measures study camparing three treatment conditions.

Treatment

I II III

4 3 8 N=12

3 1 4 G=48

5 3 6 EX2=238

4 1 6

m=4 m=2 M=6

T=16 T=8 T=24

SS=2 SS=4 SS=8

A) Calculate the sample variance for each of the three samples.

Variance for sample I=?

Variance for sample II=?

Variance for sample III=?

B) Complete the ANOVA table using two decimal places for sums of squares, mean squares, and F,

within treatments --------------- ---------------- ------------------

Total ------------ -------------- ----------------

please show the steps. Thank you so much for the help.

variance for the Data I is Var. = SS/(n-1) = 2/(4-1) = 2/3

variance for the Data II is Var. = SS/(n-1) = 4/(4-1) = 4/3

variance for the Data III is Var. = SS/(n-1) = 8/(4-1) = 8/3
