You can range by writing down all of the numbers in your set in ascending order and identify the highest and lowest numbers in the set. Subtract the smallest number in your data set from the largest number. The resulting number is the range.
The median is also the number that is halfway into the set. To find the median, the data should be arranged in order from least to greatest. If there is an even number of items in the data set, then the median is found by taking the mean (average) of the two middlemost numbers.
