7. The runs scored in a cricket match by 11 players is as follows:
7, 16, 121, 51, 101, 81, 1, 16, 9, 11, 16
Find the mean , mode , median of this data
Ans. Mean = Sum of the elements/number of elements
(7+16+121+51+101+81+1+16+9+11+16)
=
11
= 39.09
Mode is 16
Median is 16 (After arranging the numbers in ascending order 1,7,9,11,16,16,16,51,81,101,121, the middle number
is 16).
