  • The mean is found by adding up the numbers, then dividing by how many numbers you have.
  • The median is the middle of the group, so you sort the list of numbers highest to lowest, then find the number that is in the middle of the list. If the list has an even number of items, then you take the average(mean) of the two middle numbers to obtain the median.
  • Mode is the most common number or the one that occurs most often.

Each of these can be useful when evaluating real-life data.
