7. First we review
What do you remember about box plots?

8. Let’s debate

9. Standard Deviation is ...
a typical distance of the observations from their mean
is a number that measures how far away the typical observation is from the center of the distribution

10. Let’s play the standard deviation game...
Your team’s task: Create a data set of four whole numbers (from 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10) with the lowest standard deviation value possible
Input your four numbers (again use numbers from 0 to 10 only) into Stat Crunch, then calculate the standard deviation
Change a value or values until you get the lowest possible standard deviation you can. 3 minutes. Go.
Now create a data set (again only from 0 to 10) with the largest possible standard deviation.

11. B has the larger SD Which Has the Larger SD? What’s the range?
What’s the mean?
B has the larger SD

12. They have the same SD Which has the Larger SD? What’s the range?
What’s the mean?
They have the same SD

13. B has the larger SD Which has the Larger sD? What’s the range?
What’s the mean?
B has the larger SD

14. B has the larger SD Which has the Larger sD? What’s the range?
What’s the mean?
B has the larger SD

15. Calculating the standard deviation...

16. Let’s Find the standard Deviation
Let’s look at the Unit 2 test scores from another year
Let’s find the standard deviation
Let’s plug it into statcrunch and check our work
