Mean

  • put raw data into ascending order
  • add all numbers to get sum
  • divide sum by how much numbers there are
  • if you have an outlier it changes the mean

Median

  • put raw data into ascending order
  • find the middle number
  • if there is 2 numbers left add and divide by 2
  • if there is an outlier, median is the best way to find the average

Mode

  • put raw data into ascending order
  • most common data
  • you can have more than 1 mode
  • you can have no mode


Range

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








Here is a great video explaining MMM

hey leomar! good job! haha :D but you forgot to attach a link to the median and mode, and you're suppose to attach a link that explains the mean, not a game. :P just wanted to let you know. :P but still, good job!
