Answer: 6/5 or 1.2
Explanation:
To find the mean of a set of data, numbers or in this case, integers you need to add up all of the numbers and divide it by the amount of #s there are. In this case there are 5 integers/numbers and all 5 of them added up is 6.
3 + -1 + 0 + 1 + 3 = 6
Now divide that by the number of numbers you have.
6/5 and you get the answer for your average, 6/5 or 1.2
