Definition Median: So when there is a bunch of numbers you have to fin the median - (middle) to see the Median you have to count each numbers of ether side of the median number and see if there is the same amount of numbers on each side.
e.g: 1 2 4 2 8 9 0 = 2 because there is the same amount of numbers on each side
Mode definition: So if there is a 7 two times in a number sequence and there is no other double up of a number 7 will be your mode.
e.g: 1 2 7 4 7 8 it would be 7 because there is a double up of it
Mean definition: To find out the mean of the number sequence you have to add, and divided the numbers until you get the answer.
e.g: 4 5 2 so first you add the numbers 4 + 5 + 3 =12 then you dived 12 by 3 times because there are three numbers to add up so 12 / 3 = 4 because 4 x 3 = 12
