Did you get a "100" on today's vocab quiz? I sure hope so! Boost those averages before the quarter closes!
DON'T FORGET--STAMPS ARE DUE TOMORROW!
Tonight, please complete the worksheet provided in class dealing with residual plots. We will discuss each of these tomorrow...good luck! Check out some of the helpful tips below..
- If you need calculator help (for the residual plot), check out page 183 in your textbook
- For 1,2 you need to check all three conditions:
- Are the two variables quantitative?
- Are there any outliers?
- Examine a residual plot--does it show a pattern? (Make sure you sketch the residual plot to get credit on your homework
- For 3, think about how the residual plot relates to the scatterplot...this is a tough one...
- For 4, look for a pattern--if there's a pattern in the residual plot, a linear model is not appropriate.
- Number 5 is a tough question...try your best...this uses the same idea as question 3 (we'll talk more about these tomorrow)
If you're interested in getting ahead, here's tomorrow night's homework:
