Find and validate data measures eg Mean, Median, Mode and Range from appropriate displays


Median- The middle number in a set of data eg 1,2,3,4,5.

Mode- The number you see the most eg 1,5,516,.

Mean- when you add up the set of data and how ever many numbers there are you divide it by that amount eg 1+3+3+6+9+16+18=56 and there's 7 numbers so you divided it by 7 and the answer is 8.

Range- You get the lowest number and the highest number eg 1, 3,3,6,9,16,18 and you would subtract the lowest number from the highest number which is 18 - 1= 17.
