mean = sum of dataset / number of items in dataset
= (3 + -10 + -2 + 13 + 11) / 5
= 15/5

14-2 = 12 12 integers. 2 3 4 5 6 7 8 9 10 11 12 13
It's an even number, so it can't be expressed as the sum of two consecutive integers. You can however do: three consecutive integers: 41 + 42 + 43 four consecutive integers: 30 + 31 + 32 + 33 nine consecutive integers: 10 + 11 + 12 + 13 + 14 + 15 + 16 + 17 + 18. twelve consecutive integers: 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12 + 13 + 14 + 15 + 16
The sum of the squares of the three consecutive integers 11, 13, 15 = 515
Yes. In the set (9, 10, 11, 12, 13) 11 is the median and the mean.
