Description:

In this tutorial, I will cover how to carry out paired sample t-test in Python using the two packages SciPy and Pingouin. First, you will learn, however, what this type of statistical test is. Then we start importing data with Pandas.

The following parts of the tutorial cover how to carry out the dependent sample t-test in Python first with SciPy and then with Pingouin. As SciPy only gives us the p- and t-values we are also going to calculate Cohen's de by hand.
