Answer
$72.5\ ^{o}F$
Work Step by Step
Write the list in sorted order and find the item(s) in the center of the list.
$63\ ^{o}F, 67\ ^{o}F, 69\ ^{o}F, \underset\uparrow71\ ^{o}F, \underset\uparrow74\ ^{o}F, 75\ ^{o}F, 81\ ^{o}F, 83\ ^{o}F$
Since this set contains an even number of items, find the mean of the 2 center items to determine the median.
$\frac{71+74}{2}=\frac{145}{2}=72.5$
