Mean




  • Put raw data in ascending order

  • Sum of all data/overall outcome

  • If you have a outlier it can change the mean


Example



1,1,4,6,9,12=33



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



Example


Mode

  • Put raw data in ascending order
  • Most common data
  • You can have more than 1 mode
  • You can have no mode at all

Example

1,1,3,6,8,12

1 is the mode

Range

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


Example

1 , 1 , 6 , 9 ,12

1-12=11 is range

Zeeshan,
What i didn't like about your Post is that you put all the words in the color of red. You should have put black for things your trying to tell us. and Red for the title. and your spacing was kinda messed up. and i think u forgot to put a example picture for the range. Anyways Good Job! :)

Good Job zeeshan. But i agree with andrew you should have not but everything in red. Also you don't have any links to your mean median and mode, and no video.
