a) Compute the preliminary statistics below.
SSBG =  ;   dfBG =
SSWG =  ;   dfWG =
SST =  ; dfT =

b) Compute the appropriate test statistic(s) to make a decision about H0.
critical value =  ; test statistic =
Decision:

c) Compute the corresponding effect size(s) and indicate magnitude(s).
η2 =  ;  is the effect trivial, small, medium, large

d) Make an interpretation based on the results.

At least one mean is different from another.None of the means differed from one another.

e) Conduct Tukey's Post Hoc Test for the following comparisons:
2 vs. 3: difference =  ; significant:
2 vs. 4: difference =  ; significant:

f) Conduct Scheffe's Post Hoc Test for the following comparisons:
2 vs. 3: test statistic =  ; significant:
2 vs. 4: test statistic =  ; significant:

A)Statistics

SSBG =1054.393 ; dfBG = 3

SSWG = 1465.714;dfWG = 24

SST =2520.107 ;dfT=27

B)Critical value : F(3,24,.05)= 3.0088

Test Statistic : F= 5.755

Decision : Reject H0

C)Effect size = 1054.393 / 2520.107 = .4184

Magnitude : Medium effect

D)The interpretation is atleast one of the mean is different from.the others

E)Tukey test

2 vs 3 , difference = 7.2857; significance :Not significant

2 vs 4 , difference = .8571; significance :Not significant

F)Scheffe Test

2 vs 3, difference = 7.2857; significance : Not Significant

2 vs 4 difference = .8571; significance :not significant
