The median of a set of data is the middlemost number in the set. The median is also the number that is halfway into the set. To find the median, the data should first be arranged in order from least to greatest.

To find the mean, add up all of the numbers in the set and divide by the number of values that you added. Then, divide by the number of <span>values</span>
