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 out how to calculate the statistic.
Here is the link to the YouTube video: https://www.youtube.com/watch?v=GOs_IXTHT5w .
