Question

what is the mean? if the answer is a decimal, round it to the nearest tenth. -1,012 1,014 -1,014 -1,018 1,014 1,015 1,012

Explanation:

Step1: Find the sum of the numbers

$-1012 + 1014-1014 - 1018+1014 + 1015+1012$
$=(-1012 + 1012)+(1014-1014)+1014+1015 - 1018$
$=0 + 0+1014+1015 - 1018$
$=1011$

Step2: Divide by the number of values

There are 7 numbers. So the mean is $\frac{1011}{7}\approx144.4$

Answer:

$144.4$
