Here are the Fathom demos from class (you'll need a computer with Fathom installed for these two files to work):

• Least Squares Regression Line Plot both variables on a graph, then "Add Movable Line" and then "Show Squares")
• Outlier / Influential Point

And these are the powerpoint slides from today, in case you need to go over them:

• 8+9 Notes - Linear Regression WEB

Here's the nice long "cheat-sheat" reference for almost all things regression:

• 8 Notes - Regression Notes

If you missed class today (Mon/Tues), come see me for the other worksheets.

This is an OPTIONAL activity for chapter 7 (scatterplots and correlation). We may or may not have done this in your class period, but if you wish to further explore correlation with scatterplots, these are good resources.

Here are the 3 sites for the correlation half-worksheet.

1. Johnson and Kuby ACK! This one's not working... SKIP "Johnson and Kuby"
2. WH Freeman
3. Rossman Chance

And here is the half-sheet worksheet:

• 7 Worksheet - Correlation Applets.pdf 
  *if you print this out, you will get 2 half-sheets - you only need one half!
