Question: One sample has SS=35 and a second sample has SS=45.

  1. Assuming that n=6 for both samples, calculate each of the sample variances, then calculate the pooled variance. Because the samples are the same size , you should find that the pooled variance is exactly halfway between the two sample variances

b. Now assume that n= 6 for the first sample and n=16 for the second. Again, calculate the two sample variances and the pooled variance. You should find that the pooled variance is closer to the variance for the larger sample.
