The mean of a statistical data set can be obtained by using the formula

$\operatorname{mean}\text{ =}\frac{sum\text{ of all the scores}}{nu\text{mber of assignment}}$

The given scores are 89.7, 92.6, 83.9, 96.2

The number of assignment = 4

$\begin{gathered} \operatorname{mean}\text{ =}\frac{89.7\text{ + 92.6 + 83.9 + 96.2}}{4} \\ \\ \text{mean = }(362.4)/(4) \\ \\ \operatorname{mean}\text{ =90.6} \end{gathered}$
