MSB/MSW
MSB-MEan Square Between MSW-Mean Square Within |
|
|
What is MSB
|
Mean Square Between, a measure of variability between treatment groups and serves as an estimate of variability due to both error and the effects of the independent variable.
|
|
|
What is MSW
|
pooled measure of variability within each of the treatment groups. It represents a measure of variability for subjects who have been treated alike and provides an estimate of variability that is due to error only.
