Hello!
To find the mean you add all the numbers and then divide them by the amount of numbers added together
So 19+10+15+17+10+16+13 = 100
There are 7 numbers so
100/7 = 14.2
The median is the middle number when the numbers are listed from least to greatest.
So the median is 15
Mode is the number that appears the most so 10
And range is the greatest number subtracted from the least number
so 19 - 10 = 9
So the mode is 10
Median is 15
Mean is 14
and range is 9
So the answer is none of them?
Hope this helps?
