one sample has ss=36 and a second sample has ss=18 If n=4 for both samples, find each of the sample variances and compute 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. The first sample has ________ (choose one of the following 12.00, 9.00, 6.00, 3.00), and the second has s^2=______((choose one of the folloeing 12.00, 6.00, 3.00, 4.50). The pooled variance is s^2p=________(9.00,...

1. You have an independent-measures study where your first sample has an SS = 36 and your second sample has an SS = 24. a. If your sample size for both samples is n = 5, find the sample variances and compute the pooled variance. b. On the other hand, if your samples have difference sample sizes, n1 = 5 and n2 = 13. Again, calculate the two sample variances and your pooled variance. c. Compare your answers from part...
