I just finished uploading my latest lecture to YouTube. It covers how to perform one-sample t-tests and two-sample t-tests in Excel. While both are extremely important statistics, the latter cannot be easily calculated in Excel. So, I hope that this video is helpful in figuring how how to calculate the statistic.
Here is the link to the YouTube video: https://www.youtube.com/watch?v=GOs_IXTHT5w .

Although I’ve been putting it off for months (years?), I finally made a guide on performing a one-sample t-test in Excel. The “Data Analysis” add-on in Excel is not able to calculate this statistic directly, so we have to trick Excel into calculating it for us. Nevertheless, the guide provides clear instructions on how to do so.

Every semester, I try to upload my lectures to the University of South Alabama’s course management site, and, every semester, I run out of space before the half-way mark of the semester. Our IT department recently recommended that I upload my videos to YouTube to avoid these space difficulties. So, I am doing just that!
I already uploaded my first two lectures. The first is a general review of statistics with a focus on descriptive statistics and p-values. The second is an overview of one-variable chi-square tests and the chi-square test of independence (also called two-variable chi-square tests). The links are provided below:
