This table shows the size, in acres, of four large water parks. What is the median of the sizes of the four water parks? 60 acre
DiKsa [7]
The median of this list of numbers is 63.5 acres (not given).

The median of a set of data is the middle value. If you order the 4 numbers you have:

60  63  64  65

The middle is in between 63 and 64, therefore the median is 63.5.
