    These videos were very helpful. The differences between related t and independent t were explained quite well. These are great to look back at as a quick refresher before the exams. Thank you so much for posting!

    Great videos! They really help you understand the differences between what type of analysis to do if it is a related or independent t. This has been a good extension of the class. Continue to do these. I did so much better on the second test because of these and other tools you have utilized
