Median is the middle number in a sorted list of values.18 20 37 49 56Median = 37
By these factors: 1, 2, 4, 7, 8, 14, 16, 28, 32, 49, 56, 98, 112, 196, 224, 392, 784, 1568.
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.
