Hi
What is the exact formula for Scheffe's yest?
Hi
If u dont mind can u elaborate it with this anova result.
Region Mean N Source Sum of
Squares df Mean Square F
A 11.96 55 Between Gp 632.5 3 210.826 8.86
B 14.75 160 Within Gp 4425.52 396 11.1756
C 12.10 136 Total 5058 399
D 13.41 49
If I am missing any thing pls mention it.
Sorry the information is not clear.

Friends can u understand it?
@Dragan
Pls elaborate Sheffe's formula with this information.

Just take the critical value above (F_cv) and multiply it by the standard error to obtain the critical distance.
Thus, if you want to compare region 1 with 4 you would look to see if:
Ybar1 - Ybar4 >= Sqrt[((k-1)*F_.05 (k-1, dfw)]*Sqrt[MSw*(1/n1 + 1/n4)]
11.96 -13.46 >= Sqrt[((3)*2.627)]*Sqrt[11.1756*(1/55 + 1/49)].
