How do you work out the median of a set of numbers?

The median is the middle number of a set of ordered numbers, i.e. halfway along. To find the median of the data set you should arrange the numbers into order, lowest to highest. Count equally from both ends of the ordered numbers, and if the data set contains an odd number then the median is the number in the middle. If it contains an even number of numbers then you need to find the mean of the two most central numbers.For example:Data set: 12, 3, 67, 43, 6, 9,Ordered gives: 3, 6, 9, 12, 43, 67Find the mean between 9 & 12 = (9+12)/2= 10.5
