Descriptive Measures

In order to calculate measures of variation you first need to know the mean.

Group 1
m: .00
[meangroup1]
SS: .00
[SS]
s^2: .00
[SS]/5
s: .00
sqrt([SS]/5)
Group 2
m: .00
[meangroup2]
SS: .00
[SS2]
s^2: .00
[SS2]/5
s: .00
sqrt([SS2]/5)

ANOVA

Below you will find the key Analysis of Variance measures.

Grand Mean: .00
[GrandMean]
