n=6

m=6

SS=30

Avg teacher

n=8

M=2

SS=33

Good teacher

n=10

M=2

SS=42

N=42

G=72

Sigma squared= 393

*HOW DO I OBTAIN THE TOTALS FOR THE GOOD TEACHER, AVG TEACHER, AND POOR TEACHER. THEY ARE NOT GIVEN IN THE PROBLEM.

alpha level=.05

I did a one way anova independent groups test, and there was a signifcicant difference.

Summary ANOVA Table:

Source... SS...df...MS... F

Between...72...2...36... 7.2

Within...105...21...5

Total...177...23

(i aquired SS between by subtracting SStotal from SSwithin)

* Now I have to calcuate a Scheffe for this problem.

Scheffe for Poor Teacher VS Good Teacher

F= MS between/MS within=?/5

MSbetween= SSbetween/ Df between=?/2

SS between= How do I calculate SS between when I wasn't given the totals in the problem?

SS between formula: Sigma Total squared/n divided by Grand total Squared/N

I need the totals for good teacher, avg teacher, and poor teacher before I can move on to do the Scheffe test for this problem.

Sorry, if this comes off very confusing. But if you could help me I would really appreciate it. Thanks!
