Question

what is the mean? if the answer is a decimal, round it to the nearest tenth. 23 -18 -21 -10 26 27 -24 13

Explanation:

Step1: Find the sum of the numbers

$23+( - 18)+(-21)+(-10)+26+27+(-24)+13$
$=23 - 18-21 - 10+26+27-24+13$
$=(23 + 26+27+13)+(-18-21 - 10-24)$
$=89+( - 73)$
$=16$

Step2: Divide the sum by the number of values

There are 8 numbers. So, the mean is $\frac{16}{8}=2$
