Question

Answer the within-subjects ANOVA questions using the data below. Use ? = 0.01.

a) Compute the preliminary statistics below.
SSBG =  ; dfBG =  
SSBS =  ; dfBS =  
SSE =  ; dfE =  
SST =  ; dfT =  

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

c) Compute the corresponding effect size(s) and indicate magnitude(s).
?2 =  ;  ---Select--- na trivial effect small effect medium effect large effect

d) Make an interpretation based on the results.

At least one week differs on the GRE verbal score.No week is different on GRE verbal score.    

e) Conduct Tukey's Post Hoc Test for the following comparisons:
3 vs. 4: difference =  ; significant:  ---Select--- Yes No
2 vs. 4: difference =  ; significant:  ---Select--- Yes No

f) Conduct Scheffe's Post Hoc Test for the following comparisons:
1 vs. 4: test statistic =  ; significant:  ---Select--- Yes No
1 vs. 3: test statistic =  ; significant:  ---Select--- Yes No

Explanation / Answer

A. SSBG = 778.3929; dfBG = 3. SSBS = 1506.8571; dfBS = 24; SSE = 1506.8571; dfE = 24. SST = 2285.25; dfT = 27.

B. Critical value = > 0.05. Test statistic = The f-ratio value is 4.1325. Decision = Reject the H0.

C. ?2 = 0.34; Medium effect size.

D. Interpretation: At least one week differs on the GRE verbal score.
