Answer:

Mean: 20.83

Median: 21

Mode: All numbers

Range: 19

Step-by-step explanation:

First of all we would arrange these numbers in ascending order - 12, 15, 20, 22, 25, 31.

Mean = sum of all observations/total no of observations

= 125/6

= 20.83

Median

As total no. of observations is even so median would be the mean of (n/2)th term and (n/2+1)th term. Here n = 6.

n/2 = 6/2 = 3

n/2+1 = 6/2+1 = 6+2/2 = 8/2 = 4

So the median would be the mean of 3rd and 4th term.

= 20+22/2

= 42/2

= 21

Mode = The observation occuring most no. of times. As here all the observations are occuring equal no. of times, so all numbers are mode.

Range = Difference of largest and smallest value

= 31-12

= 19
