  • add all the numbers in the set of data

  • then divide the sum by how many numbers there are



  • find out the middle number(s) then add them up

  • then divide the sum by 2

  • if there isn't 2 numbers you can add up then the that number is auto maticly the median


Mode :

  • you can find the mode by looking at the set of data and searching for the number that shows up the most


Range :

  • you can easily find the range by putting the set of data in ascending order

  • then subtract the largest number with the smallest data
