That said, if you were not expecting the distributions to be (that) different, now is a good time to make sure you're measuring what you think you're measuring, i.e. you are feeding in the right data to scipy. Share Improve this answer Follow WebThe Student’s paired samples t-test (sometimes called a dependent-samples t-test) is used to test the null hypothesis that the difference between pairs of measurements is equal to zero. A low p-value suggests that the null hypothesis is not true, and that the difference between the measurement pairs is not zero.
