The median is the number in the middle. When you have a even number of numbers, as we do here, we take the mean of the two middle numbers. First put the numbers in ascending order. We have 20 37 49 56 . Since 37 and 49 are the two in the middle we take their mean. 37+49=86 and half of that is 43 so this is the median.

To find the median of a set of numbers, you first need to arrange the numbers in either ascending or descending order. Once the numbers are arranged, the median is the middle number in the set. In this case, when the numbers are arranged in ascending order, the set becomes 43, 44, 45, 47, 48, 49, 49, 52, 53. Since there are 9 numbers in total, the middle number is the 5th number, which is 48. Therefore, the median of the given set of numbers is 48.
The median is 52.
