1, 1000, 40, 41, 39,40,40,39,41
31,49,74,26,54,36,55,19
Try those.
@bobpursley thank you very much. I tried those data sets but it didnot work :(
Try 75, 25, 50, 51, 52, 49, 48, 50, 50, 49 for your first equation and
61, 39, 62, 38, 63, 37, 64, 36, 65, 35 for the second.
I have made the distributions with mean = 50 and n = 10 to make the calculations easier for you.
The range only relies on the two most extreme scores, while the SD includes the variation from the mean of all scores.
