Susan's grades8,8,7,9,7,8,8,6,8,7,8,8,8,7,8,8,10,9,9,9 roughly what is a typical distance from the mean for susan

Answer 1

You can find the mean by adding all the grades up to get 160, and there are 20 grades, so the mean is 160/20 = 8.

Just visually "inspecting" the list, it appears typically Susan's grade are about a distance of 1 from the mean... some are exactly 8, so zero distance... some are 9, some are 7, and only one is 6 and only one is 10.
