In this video Paul Andersen explains how to run the student's ttest on a set of data. He starts by explaining conceptually how a tvalue can be used to determine the statistical difference between two samples. He then shows you how to use a ttest to test the null hypothesis. He finally gives you a separate data set that can be used to practice running the test.
