  • 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
