1.) Take the time to look over the sample responses for describing the distribution of the number of chocolate chips per bag of Chips Ahoy cookies--I'd even recommend copying one down (not the one with the incorrect histogram) on your quiz--this will help you to retain this info more, and will force you to compare your response to a perfect one as you copy!
2.) Want more practice describing distributions? How bout a little extra credit homework--this will only be accepted tomorrow!
Homework due Friday -- please complete the following in your textbook:
- If you're looking to get a head start you can probably do some of this tonight, like some of #5, 27de, and 37e
Page 91: 5, 7, 17, 27de, 29, 35abc, 37de
- For #5 you're not calculating anything--your job is to determine what would happen to each summary statistics--would they increase, decrease, or stay the same? Why?
- For 7cd and 17 consider the "appropriate summary statistics" info we discussed today in class!
- For 27de consider today's notes about spread!
- I know we've looked at 29ab before--revisit this question and try to be more specific, use specific stats vocab (you don't necessarily have to write anything, but think about this!)
- For 27cd--back to "appropriate summary stats"-- and the "why" is simply referencing the shape of the distribution!.
- For 37d you need to use the 5 number summary to try to decide if this is skewed or symmetric (we can't figure out the modality from this info)--consider our notes on describing the shape of a boxplot!
- For 37e be sure to reference these summary statistics as your support when you "explain." Try to comment on percentiles with statements "___% of boys/girls had a higher reading level than ___% of boys/girls."
Tomorrow in class we'll finish talking about standard deviation, discuss some ogives and how to compare boxplots--then Friday we'll do some work with comparing distributions and we'll revisit that free response--see you there!
