      You are welcome Keira. Thanks for the suggestion. I have a couple of videos on R (on a couple of specific topics). More R videos have always been part of the plan, but I'm a little tight on time these days. I'll try to get some up for the next offering. Best of luck on the test!

    how will standard deviation of a set of discrete data change
    -when a value that is equal to the mean is added to data
    -when a value less than one standard deviation from mean is added to data
    -when a value that is more than one standard deviation is added to data?

      A bit late to help, but maybe this comment will help others in the future. You subtract the n-1 first then divide.
