Descriptive statistics describe data series using key figures. Some of these are the mean, median, mode, and range. The mean of n numbers is the sum of the numbers divided by n. If you order the n numbers according to size, the median, if n is odd, is the middle number. If n is even, the median is the mean of the two middle numbers. The mode, on the other hand, represents the most frequently occurring number. However, it is not always unique, a data series can have several modes. The range is the difference between the largest and smallest number.
