If you missed the review day (Th/F, Oct 18/19), here is the rundown:

First, here is the test review, due on the day of your exam (scheduled for M/Tu, Oct 22/23):

• Review Unit IV (Scatterplots & Regressions) [due M/Tu, Oct 22/23] (answers are at the end)

Also, there some very brief notes on the effect of outliers on the slope of the regression line and the correlation coefficient:

• Powerpoint 4.3 - Outliers with Scatterplots

Finally, here is the one practice problem that we worked in groups:

• Worksheet - Gesell Scores vs Age at First Spoken Word (check answers with us in tutorials if necessary)

For F/M, Oct 12/15, we continued with scatterplots and also covered computer printouts. Here are the handouts:

• Powerpoint Slides: More Linear Regressions
• Worksheet - Computer Printouts (Pg. 188 in the textbook has a good explanation for how to get slope and y-intercept from these. #1 and 2 are done for you - complete 3 and 4)

Here is the worksheet for homework (there are also some textbook problems as well):

• Worksheet (HW #20) - Linear Regressions

Here are the notes/slides/handouts/etc for W/Th, Oct 10/11:

• Powerpoint Slides: Scatterplots & Regressions I
• Blank copy of notes (The reference notes on the back side are very helpful!)

And in case you want to get an EARLY start on NEXT TIME'S homework worksheet, here it is:

• Worksheet HW #20 - Linear Regressions - THIS IS NOT TODAY'S HW! THIS WILL BE GIVEN OUT NEXT CLASS!
