(21+15+19+28+10+17+9+15+26+14+10+18+24+12+16) / 15 = 16.93 recurring (that is, 16.93333...)
It is: 14+15+22+21 = 72/4 => 18 which is the mean average

There isn't one.

It is 15.
There isn't one.
Order them: 15 16 17 21 21 Find the middle one: 17 That is the median
Sum = 85 Number = 5 So mean = 85/5 = 17
Then number half way between them is their mean average: (-3/7 + -15/14) ÷ 2 = (-6/14 + -15/14) ÷ 2 = -21/14 ÷ 2= -21/28 = -3/4
16+17+21+15+139=208
16.5 is the median.
