2.  I can identify the shape of a data distribution using statistics or charts.  I can make inferences about the population from the shape of a sample.

3.  You have 4 minutes to roll a pair of dice as many times as possible. Make sure to keep track of the sums that you roll!

4. Mean: the average of a set of data Add all of the values up and divide by the total number

5. Standard Deviation: A measure of variation from the mean Remember, is the mean.

7. Graphing data on a Histogram The Independent Variable (what you are changing) goes on the x-axis The Dependent Variable (the result of your experiment) goes on the y-axis

8.  Use your personal data to create a graph  One at a time, come to the computer and enter your data into the spreadsheet

10.  What does it look like?  Why is it called a bell curve?  What does “normal” mean?  What makes a set of data “normal”?

13. Is your data normally distributed?

14. Mean = 490 Standard Deviation = 100

15.  Is the data normally distributed?  Does the sample size have an effect on the normality of the data?
