Tuesday HW = Prep for New Unit!

I hope you're feeling confident about today's test! If you were out, today we completed our Unit 1 Test (which you'll have to make up after school, during lunch, or during study hall); tomorrow in class we will start our next unit, Linear Regression! (see below)

Tonight you should review your AP Stat Summer Academy Notes about linear regression--you need to know all the stuff below by the end of Friday (at the latest), as we'll only spend about 3 days on chapter 7! This content will be quickly reviewed, but not entirely re-taught in class--and we'll have a quiz sooner than later, so be proactive! This unit gives us all a fresh start (content wise), so start strong tonight! Review this info and prepare yourself to ace this unit!

• Watch AP Stat Guy Videos to review (or learn for the first time) the AP Summer Academy Regression stuff!
• Go to AP Stats Guy, scroll down to Unit 2, then watch videos 1,2,3,4, and 8.
• Read through chapters 7 and 8
• We'll take notes on these chapters in class, but we covered parts of each chapter in our summer academy!
• Ultimately, here's what we covered in the summer (and thus, what you should know/review):
• Sketch a scatterplot using your calculator
• Identify explanatory/response variables in a scatter plot
• Find r, R^2, and the equation of the least squares regression line, or LSRL, (line of best fit) using your calculator
• Describe an association (notes tomorrow)
• Use the equation of the LSRL to make predictions
• Calculate a residual (actual - predicted)
• And here are the two assignments we completed in the summer academy--you should be able to answer these questions (study this stuff)!

See you all tomorrow! One unit down, six to go!
