Question: One sample has SS = 32 and a second sample has SS = 48.

(a) Calculate the variance for each sample and the pooled variance, assuming that n = 5 for both samples. You should find that the pooled variance is halfway between the two sample variances.

(b) Now, assume that the first sample has n = 9 scores and the second has

n = 4. Calculate the variance for each sample and the pooled variance. this time you should find that the pooled variance is closer to the value for the larger sample.
