The data from an independent-measures research study produce a sample mean difference of 4 points and a pooled variance of 18. if there are n = 4 scores in each sample, what is the estimated standard error for the sample mean difference?

3

Step-by-step explanation:

Given : Pooled variance :

Sample sizes of each sample =

We know that the standard error for the sample mean difference is given by :-

Hence, the estimated standard error for the sample mean difference =3
