    Thank you thank you Miss Kathy. After 15 years i find myself taking this elementary statistics class and you are the only one that gave a full walk through for us who have not picked up a math book in years. Please keep up the videos we need them.

    thanks! I was stuck on 1 problem for literally 2 hours trying to figure it out. This was the only video I could find explaining it!

    Wow. I tried to look in the book and my professor's notes for the past two hours, and I was super frustrated -- you are amazing!

    Thank you so much! This really helped! I knew how to do the problems on StatCrunch but had to figure out how to do it by hand and I'm glad I found you after endless time trying to figure out how to solve this set of problems.

    These videos were originally created for a flipped class. A few years ago some changes were made at my college that resulted in the end of my flipped class. Therefore I have not been checking these videos for comments for a few years. Now that Covid-19 has moved all of my classes online, I have an opportunity to use these videos once again and to be more responsive to people who watch them.

    Taking online courses and the book really does explain in Detail how to get the results. I searched and found your video. Thanks for breaking it down.

    Thanks so much! Definitely helped me understand the problem I'm working on better than any other video I could find. It might be helpful to note that the probability of each respective variance will only be (number of samples that result in that variance)/(total possible samples) if each sample has an equal probability of occurring. If the problem gives a joint distribution table, it's necessary to sum up the probability of all samples that have the respective variance.

    Hello. Thank you for your video. I am confused why did you subtract 2-1 Wasn't it suppossed to be 3-1 because you have 3 numbers the 5,7,12. Thanks I am stuck with this homework

    • @kathyarcangeli3203

      The formula has n - 1 in the denominator. n is the sample size. The population size is 3 but the sample size is 2.
