mean = 19.833... median = 19.5 mode = 19
(21+15+19+28+10+17+9+15+26+14+10+18+24+12+16) / 15 = 16.93 recurring (that is, 16.93333...)
I added up all the numbers to get 126, then i divided that all by 7 to get 18. your final answer is 18.

The mean = The sum of all the values ÷ The number of values. 18 + 15 + 22 + 18 + 25 + 19 + 23 = 140 : Number of values = 7 Mean = 140 ÷ 7 = 20
The mean is 19. The median is 18. There is no mode.

mean = 19.833... median = 19.5 mode = 19
the answer is 30 its the sum of all these numbers then divide by 2

They are 15, 16, 17, 18 & 19.
(21+15+19+28+10+17+9+15+26+14+10+18+24+12+16) / 15 = 16.93 recurring (that is, 16.93333...)
20.37 is the mean.

Mean (12, 18, 19, 20, 21) = 18
