Question

What is mean average of 17,12,8,4,6,1,12,16,16​

Answer 1

All these numbers give a total of: 92

There is a total of 9 numbers, so we have to divide 92 by 9

92/9=10.2 (to 1 dp).

Therefore the mean is 10.2

Answer 2

The mean is equal to the sum of the values over the total number of values.

17+12+8+4+6+1+12+16+16=92

The number of values is 9

92/9=10.2222

The mean/average is 10.2222.

Hope this helps!!
