To determine the median of a data set, you need to put all of the values you have in their numerical order. Count how many figures there are overall, if there is an even number, then the median will be the middle number. if there is an even number, then to find the median number you need to determine the mean of the two numbers in the middle. To determine the mean of a data set, you first need to add together all the values within the set. Next, count up how many overall values there are, and then divide the previous total by the number of values that there are.
