18. Paired T Test

In this video, we dive into the paired t-test, a statistical method used to compare the means of two related groups, often measured at different times or under different conditions.

We explain the step-by-step process, including how to calculate the differences, mean, standard deviation, and t-statistic.

You'll also see an example where we test whether a new study technique improves test scores.

By the end, you'll understand how to interpret results and make decisions about accepting or rejecting the null hypothesis.

Perfect for students and researchers working with paired data!
