The median in that list of numbers is 28. It is the average of the middle two numbers in the list, when the numbers are written in order from least to greatest.
To figure out the median number, follow these steps. First, order the numbers from least to greatest. Second, cross off numbers from both sides until you end up with two numbers in the middle. Then, average these two middle numbers by adding them together and dividing the sum by two.
In this case, the list is 14, 17, 27, 28, 28, 29, 32, and 45. The middle two numbers are 28 and 28. The average of 28 and 28 is 28.
