for the record...

Mean, median, and mode are technically all different types of average.
  • mean is what is most commonly meant by average: add all the numbers together and divide by how many.
  • median is the slightly complicated one where you sort all the numbers in your list and then take the one that's in the middle (or average the two in the middle, if the quantity of numbers you have is an even number).
  • mode is where you look for the most common number, even if it's nowhere near the "average". In this series -- 1,2,3,4,100,100,100 -- the mode would be 100. Mode is only useful in certain circumstances.
