If one sample has n = 5 scores with SS = 40 and a second sample has n = 5 scores with SS = 20,then the pooled variance will be 60/10 = 6.

Question

​If one sample has n = 5 scores with SS = 40 and a second sample has n = 5 scores with SS = 20,then the pooled variance will be 60/10 = 6.

Quizplus · Accepted Answer

The pooled variance is calculated by dividing the sum of the squared deviations for both samples by the degrees of freedom, which is n1 + n2 - 2. The correct calculation for pooled variance in this case is (40+20)/(5+5-2) = 6. However, the question incorrectly states that the pooled variance is 60/10.
