Re: Need to calculate confidence for an A/B test with excel
The only numbers I have are:
Test A: total number of visitors and the percentage that took the desired action.
Test B: total number of visitors and the percentage that took the desired action.
What I'd like to end up with is a result that says "given the sample size of the test, you can be XX% confident that future results will be within YY% of the current results regardless of how much larger your sample size gets."
