One sample has ss = 60 and a second sample has ss = 48.

if n = 7 for both samples, find each of the sample variances, and 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

The pooled variance of the samples estimates the weighted variance of the samples

The pooled variance is 2952

How to calculate the pooled variance?

The given parameters are:

  • Sample 1:

n = 7

ss = 60

  • Sample 2:

n = 7

ss = 48

The pooled variance is calculated using:

Sp = [SS1^2 *(n1 - 1) + SS2^2 *(n2 - 1)]/[(n1 - 1) + (n2 - 1)]

So, we have:

Sp = [60^2 *(7 - 1) + 48^2 *(7 - 1)]/[(7 - 1) + (7 - 1)]

Evaluate the expression

Sp = 2952

Hence, the pooled variance is 2952
