Math

Yesterday in math we learned about range, median, mode, mean.

Mean- the average number in a group of numbers. To find it, add all the numbers together and then divide by the amount of numbers.
Mode- the number that occurs the most. You just have to find the number that appears the most. It is fine to have more than one number.
Median- the number that is in the middle of a group of number that are arranged in order. If there are two in the middle, add them together and divide them by 2.
Range-the difference between the lowest and highest numbers.
