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.
I did a one way anova independent groups test, and there was a signifcicant difference.
Summary ANOVA Table:
Source... SS...df...MS... F
(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!
