Find the Average!

Sixth grade students are working on finding different froms of the average of a set of numbers. Below is a list of the forms they have been working on. There is a quiz on averages this Friday.

Median- the middle number of an ordered set of numbers. If there are two numbers, add the numbers and divide by 2.

Mode- the number that happens the most

Range- the difference between the biggest and smallest number (biggest-smallest)

Mean- add all numbers and divide by how many numbers there are
