The sum of squares within is equal to the sum of squares total minus the sum of square between. true True false False. Ths is true because the sum of squares total is the sum of squares between and the sum of square within. When the sample means are very close the sum of squares between is false close to the sum of squares within Choose blank dataset and then add data by clicking with the mouse. The red lines represent the group means. Add data so that the red lines are at approximatelt at the same height. true close to the 0 If the sample means are exactly equal then the sum of squares between will be 0. An F ratio is computed by true dividing the mean square between by the mean square error. false dividing the mean square between by the mean square total. false dividing the mean square between by its df. dividing the mean square between by the mean square error. An mean square is computed by false subtracting the smallest mean from the largest mean. true dividing a sum of squares by its degrees of freedom. false dividing the mean square between by its df. dividing a sum of squares by its degrees of freedom.
