SOLUTION
Let's list the values first. These are
48, 65, 60, 45, 54, 64, 70 and 45
Now, we have to arrange these values from the smallest to the largest. Doing this we have
45, 45, 48, 54, 60, 64, 65, 70.
The median will be between the middle items which are 54 and 60. So we will find the median by the following way

Therefore, the Median is 57°F
