I use VAR function in Excel sheet, to calculate the variance for the values (0,1,2,2,3,4,5,6,7,9,16) as in the video but, the result was 20.6 not 18.73 as mentioned in the video, kindly review and inform me if I am wrong

Hi Fathy, Thank you very much for raising our attention to this issue. I recalculated the variance myself and it turned out that you are right. I will ask the team to make the necessary changes in the video. Thanks again, Olivier
