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. <span />
