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

$\displaystyle\frac{{{88}+{81}+{93}+{85}+{98}}}{{5}}=\frac{{445}}{{5}}={89}\usepackage{cmbright}\Huge\$

To find the median, arrange the values in order from least to greatest and identify the middle value: 81, 85, 88, 93, 98. The median is 88.

The mean with a value of 89 is larger than the median whose value is 88.
