The sum of squares between groups is affected by:
The differences of individual points from group means affects the sum of squares within.
true
sample size
false
differences between data points and their group mean
true
differences among group means
Adding a data point will never decrease the sum of squares within.
The mean square within can be lowered, but not the sum of squares within.
true
True
false
False
The mean square within can be lowered by adding a point that is
The mean square within is calculated by taking squared deviations of scores from their own mean.
true
close to the mean of the group it is in.
false
equal to the mean of all data for all groups.
The group means are all equal. The sum of squares between is:
The sum of squares between is based on differences among means. If the means are equal, the sum of squares is 0.
0
0
The mean square between is the variance of the group means.
It is the variance of the group means multiplied by n.
