Question

For each of the following, calculate the pooled variance and the estimated standard error for the sample mean difference.

The first sample has n =4 scores and a variance of s²= 55, and the second sample has n = 6 scores and a variance of s² = 63.
Now the sample variances are increased so that the first sample has n ‑ 4 scores and a variance of s² = 220, and the second sample has n = 6 scores and a variance of s² = 252.
Comparing your answers for parts a and b, how does increased variance influence the size of the estimated standard error
