      not a practical method for finding the median. If n represents the number of data points in a distribution, then: the position of the "middle value" is ! n+1 2. If the data points have been arranged numerically, we can use this fact to efficiently find the median. EXAMPLE For the following list, n = 19. Find the median.

Figure out the mean, the mode (if there is one), and the range. What is the median? It’s halfway between the two middle numbers. (If those are 2 and 3, the median in 2.5, for example)

      To find the quartiles and median, put the numbers in order from smallest to largest. Then if there are an odd number of numbers in the list the median can be found by counting in from either end of the list to the (n + 1)/2nd number. This will be the median. If there are an even number on the list then average the n/2 and the (N +2)/2 numbers.
