Answer 2

Range = Highest observation - Lowest observation

Range = 21 - 13

Range = 8

Mean = Sum of observation/ Number of observation

Mean = 13+18+13+14+13+16+14+21+13/9

Mean = 135/9

Mean = 15

Mode = The observations with the maximum frequency is called 'Mode'

13,18,13,14,13,16,14,21,13

=> The mode of this data is 13.

Median = For finding median arrange the data in ascending or descending order.

=> The ascending order of the data is:

=> 13,13,13,13,14,14,16,18,21

The middle value is 14.

So,the median of the data is 14.
