Homework Help: statistics

Posted by Genova on Monday, April 7, 2008 at 2:50pm.

Poor teacher
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!
