Thursday....

Tonight's HW (hopefully you did some last night so you can enjoy Halloween!)

• Pages 214-217 : 7, 9ce, 11, 13, 15a, 
• For #11 you need to answer questions 1, 3, 4 for each scatterplot
• You don't need sentences; you can structure your answer like this for each scatter plot
• Sample answers (how to do 11) based on #12: the stuff in italics is "extra"
• a.) 1.) high leverage and high resid  3.) point removed, r stronger (r increases); 4.) point removed, slope increase (line steeper)
• b.) 1.) high leverage  3.) correlation stronger (becomes +)  4.) slope would increase (steeper)--line would go from horizontal (no association) to a positive slope
• c.) 1.) high residual 3.) correlation would decrease (weaker)  4.) slope would stay about the same (b/c point has no leverage)
• d.) High leverage    3.) correlation would be stronger (decrease because it's negative and r gets closer to -1)  4.)  slope would stay about the same (because the point is close to the LSRL) 
• Want more review for our test?
• Do all of #9!
• Do 15cde

Tomorrow is your last chance to turn in stamps; if you don't have them counted/ready to go tomorrow you will earn a 0! Check yesterday's blog post for instructions.

Your next AP Classroom assignment has been assigned (MC and FR); this is due at midnight Wednesday; it's a great way to study for our test AND your MC score will count as a grade!

• You can just do the Free Response to study on your own--do them on separate paper and use the key below to check your work!

• Unit 2 Progress Check: Free Response KEY! (Click Me)

And here's the plan for the rest of the unit (this week and next week):

• Fri (11/1): Outliers, Leverage, Influential Points + Re-expressing data (ch. 9)
• Mon (11/4): Classwork/Practice (Influential Points and Re-expression) (I'm really hoping we finish our notes tomorrow)
• Tues (11/5): No school (Election Day)
• Weds (11/6): Unit 2 Vocabulary Exam (25 min) + AP MC (Ch. 9, 10)
