Mean


  • put raw data in ascending order
  • add up all data

  • divide the sum by how many datas there are


Median


  • put raw data in ascending order
  • median found as the middle number

  • if two numbers are in the middle

  • add those two numbers up

  • and then divide by 2

Mode

  • most common data(data that appears more often)

  • you can have more than 1 mode

  • you can have no mode at all

Good job Frank. I think your line spacing needs to be closer so it's more organized. But I liked the big pictures. Good job.
