Mean
  • put raw data into an ascending order
  • the sum of all numbers divided by the number of data


Median
  • put raw data into an ascending order
  • the number in the middle of the data in ascending order
  • there can't be 2 medians
  • if there's 2 numbers in the middle, add them together and divide by 2


Mode

  • most common data
  • you can have more than one mode
  • you can have no mode

  • put raw data into an ascending order
  • largest data minus the smallest data
