Range: take the largest number and subtract the smallest number you have
Mean: add all the numbers together and divide it by the amount of numbers there were
Mode: the number that appears most often so multiple times
Median: To find the median, put all numbers into ascending order and work into the middle by crossing off numbers at each end. If there are a lot of items of data, add 1 to the number of items of data and then divide by 2 to find which item of data will be the median.
