There are 3 data sets given as

   Frequ                  1  2  1   2  2 0     2

Mean dev|x-10|*f    3 4  1   0    3  0   6      17

II)     x                         7 8 9 10 11 12 13    Total

   Frequ                     2  3 0  0  1  1   3

Mean dev|x-10|*f        6  6  0  0 1  2 9     24

III)   x                         7 8 9 10 11 12 13    Total

   Frequ                     0 0 4  4  1  0 1

Thus we find the middle one Jason has the highest deviation.
