Using the table below, find the mean and median of the set of data.
Schach [20]

The mean of the data set is 81.6.

The median of the data set is 80.

<h3>What is mean?</h3>

The mean is the average of a data set. Therefore,

Mean = (70 x 2 + 75 x 8 + 80 x 6 + 85 x 3 + 90 x 9) / 28 = 81.6.

Hence,

mean = 81.6

<h3>What is a median?</h3>

Median is a statistical measure that determines the middle value of a dataset listed in ascending order .

Therefore,

28 / 2 = 14

median = 80 + 80 / 2 = 160 / 2 = 80
