Can someone please advise how does one computate an estimate of population variance based on the variance of the sample means. I am not sure how to calculate this. I can not figure out how to arrive at the solution to several examples of this same type.

Variance of the sample means is equal to population variance divide by n, the sample size. Therefore population variance = var_mean*n

Quark,
Thank you for your response. one of the issues I am having is how to arrive at the popultion varience or am I looking at the wrong data in the problem. I have, according to what I am working with, a list of sample size, sample means, and sample varience. likewise, I can find the mean square for error(within the groups) but I can not find the mean square for treatments (between the groups). here lies my problem.

[quark]

If you have the ANOVA table, MST (mean square for treatments) should be the number above MSE. MSE is an estimate of the variance of the sample means.

Greetings Quark, I do have the chart but what I want to know is exactly how to get that particular figure. the chart I have has figures on it but doesn't explain the step by step solution at getting that figure. (MSE oe SSE as my chart refers to it).
