@PhilosophyExp I think the calculation is wrong. It's the right formula for the two-sample t-test, but the answer is 0.699 for values given.1 reply 0 retweets 0 likes -

@PhilosophyExp If you put the raw data through the excel TTEST function you get 0.22 - but that's the p-value not the t-value.1 reply 0 retweets 0 likes
