Hey Andrew! Thank you so much for posting this video! I found it SO USEFUL! I didn't even realize I could do that on the calculator. I do have a question though. The video explains how to get the mean from inputting the data. Let's say I have a list of 40 values. Is there a way to find the mean and then find the median without having to retype the entire list again?
