The Bell Curve is a way to show the distribution of data. It uses the standard deviation and the average to show where the data falls

Each unit on the number line moves up or down by one standard deviation. You add if going to the right, and subtract if going to the left

EXAMPLE!Given a mean of 17 and a standard deviation of 4, what does the bell curve look like?

17

21

5

9

13

25

29

Where does 10 fall?

10 falls between one and two standard deviations below the mean!

Where does 27 fall?

27 falls between two and three standard deviations above the mean

What about percentages?This tells us how much of the data falls between each range. These percentages never change!

How much data?!?If you were given the following data, which numbers would fall between zero and one standard deviations ABOVE the mean?

10 18 19 24

18 and 19 work!
