Mean is the sum of the numbers in a set of data divided by the number of pieces of data (average).

 

 

Add all the numbers to get the sum (9+12+15+20+22+30= 108), and then divide the sum into the total amount od data, which is 6, to get the mean (108/6= 18).

Median is the middle numbder of the set of data that is arranged in numerical order.

--> When there are two middle numbers, the median is thier mean.

Look at this. The Lever is getting smaller when it reaches the middle. This picture is showing where the middle is.

If you have 2 medians, multiply them together (5x5= 25), then divide the answer into 2 to get the median because there are only two numbers, which is 5 and 5

(25/2= 12.5).
