Understanding the one-sample T-test

Description: In this lecture, we cover the one-sample t-test, including how to distinguish between different types of t-tests used to test the difference for one sample or between two samples, and perform statistical tests for one-sample hypotheses. We also explain the difference between the t-test and the z-test, the research questions and the distribution curve we use.
