These values are then automatically inserted into their corresponding fields in the form. You are then free to enter whatever you like for α and "pooled?" to continue.

oh! That is absolutely marvellous, thanks very much indeed Smile

yes, works perfectly. No need to reach for the Prime and its Import function any more Smile

thanks again, great stuff.

Noted re caveats.

Strictly speaking there is no need for the sample sizes to be the same for a Student's t-test, I think, but if you had different sizes samples you'd not be able to deal with them together in ΣDAT, anyway (e.g. the MTWR will insert a 0 for an empty element), so in that case you'd have to do it entirely differently.

In my case, the samples are generally the same size, so your method works perfectly, thanks again.
