Significance testing
I have a much larger dataset, but this is a smaller version. I want to look by question at the result score for those answering yes against those answering no, in the full dataset the variances in the two samples are similar, but the sample size is quite variable. I was hopeing to use a 2 tailed T test to test the null hypothesis that the means of the two samples are the same. Ideally i would show the differences between the means and the confidence level.

Hi guyscottsouth,
I recalled my statistics. I don't know if this could help. Maybe you review it first, then we could go further. Please check this file:https://1drv.ms/u/s!ArTqPk2pu-BkgRFQZ5z_1PDA0QpQ.
Best Regards!

This is awesome Dale. Are you by chance available at all to work me though how I might re-create this to generate a template table I can use on all or most of my data sets?
