Step 1:
Draw a table to find the mean
Next, find the mean.
[tex]\begin{gathered} \operatorname{mean}\text{ = }\frac{\sum ^{}_{}Pf}{\sum ^{}_{}f} \\ \end{gathered}[/tex][tex]\text{Mean = }\frac{394}{32}\text{ = 12.3125}[/tex]
Step 2: Median
The median is the middle number when the sets of data are arranged in ascending order.
8, 8, 8, 8, 8, 9, 9, 9, 9, 9, 10, 10, 10, 11, 11, 14, 14, 14, 14, 15, 15, 15, 15, 15, 15, 15, 16, 16, 16, 16, 16, 16
Median is the mean of 14 and
