I got ten research studies with means and sample sizes. I am classifying the ten studies based on its characteristics into two sub groups each having five studies. I have worked grand mean for each sub group. Now can I check whether grand mean of two sub groups significantly different or not through t test? Share reading materials also.
I don't think so. Download Ingram olkin's classic book shown in the attachment from the z-library for a start.

Hello Thirunavukkarasu D. Here is an online calculator you might find useful.

Bruce , Thanks very much for the calculator. But I prefer to know how my models are built a bit more precisely than that output would tell me. I once read a comment by Frank Harrell that was in a different context but a modification may apply here BTW I forgot whom he said originally made the statement but it was "A journey of a thousand assumptions begins with a single stepwise regression". Maybe here the same idea applies. Best wishes, David Booth
