To find the mean, add the scores and divide that sum by 5, the number of scores:

$\displaystyle\frac{\text{96 + 77 + 82 + 96 + 89}}{\text{5}}=\frac{{440}}{{5}}={88}\usepackage{cmbright}\Huge\$

To find the median, arrange the values in order from least to greatest and identify the middle value: 77, 82, 89, 96, 96. The median is 89.

The mean of the set is less than the median.
