Mean Square

[Back to Statistics Contents]
In an ANOVA, the term Mean Square refers to an estimate of the population variance based on the variability among a given set of measures.

In a one way ANOVA, the Within Mean Square is an estimate of the population variance based on the average of all s-square within the several samples.

In a one way ANOVA the Between Mean Square is an estimate of the population variance based on the s-square of the sample means multiplied by n (the size of the samples).
