Question

what is the mean? -2 -1 0 -5 1 -1 0 8

Explanation:

Step1: Sum the numbers

To find the mean, first we sum all the given numbers. The numbers are \(-2\), \(-1\), \(0\), \(-5\), \(1\), \(-1\), \(0\), \(8\). Let's calculate their sum:
\((-2)+(-1)+0+(-5)+1+(-1)+0+8\)
\(= (-2 - 1 - 5 - 1)+(0 + 0)+(1 + 8)\)
\(= (-9)+0 + 9\)
\(= 0\)

Step2: Divide by the number of terms

There are \(8\) numbers. The mean is the sum divided by the number of terms. So, mean \(=\frac{0}{8}=0\).

Answer:

\(0\)
