3. What are ways we can analyze this data to make it mean something?

1, 4, 1, 0, 6, 0, 1, 3

8. Standard Error of the Mean
Standard deviation deals with the deviation from each individual measurement from the mean
Standard error of the mean deals with the deviation of the mean from the ‘true’ mean

9. 2SEM
On the AP exam you will be expected to understand why we use ‘2xSEM’
Multiplying the standard error of the mean by 2 means we will be hitting 95% of our measurements
Also called a 95% confidence interval

11. Error Bars

12. Error Bars
If error bars overlap on the graph then the means are not statistically different
If they DO NOT overlap then the means ARE statistically different
