Range: Take the highest number and lowest number and subtract them. Median: Put the numbers in order from least to greatest and find the number in the middle by crossing off one from each end until one number is left. If two are left, take the average by adding them together and dividing by two. Mean: take the average by adding all the numbers up and dividing by the amount of numbers. Mode: What number do you see the most times? (here, each number is used once, so there is no mode).
