      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!

    hi, thanks for this video
    I have a question, if 0 is part of the sample , do you include it as calculating the mean. The numbers in my data are as follows (0,1,2,3,5,8). Do I include 0 in my calculations

  • @ahamedakmal7104
    @ahamedakmal7104 7 ปีที่แล้ว

    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.
