The mean of $-101,100,101,102$and $98$ is_____

We know that,

$Mean=\frac{Sumofallobservations}{Totalnumberofobservations}$

Given data is $-101,100,101,102,$$98$

Here, number of observations $\left(n\right)=5$

Therefore,

$\begin{array}{rcl}Mean& =& \frac{-101+100+101+102+98}{5}\\ & =& \frac{300}{5}\\ & =& 60\end{array}$

Hence, mean of $-101,100,101,102,$$98$ is $60$
