Thread: How to Calculate the Minimum Binomial Sample Size?

A colleague of mine is about to do a validation study of some diagnosis given. In this study either the diagnosis is correct or it's not, i.e. it's a binomial trial. We assume that about 90% of the diagnoses are correct given. My question is how do we calculate the minimum sample size?

Can you be a little more clear? I am not sure that you are giving us all the information necessary to be able to answer your question. Are there specific standards for this certain study? Maybe you should tell us about the actual population size for which you need the sample.

Sounds like a statistics problem. Hopefully this will be of help: How to Calculate the Minimum Binomial Sample Size | eHow.com

Did that see you right?

This isn't homework is it?
