On Monday we'll start our first full week of "real AP Stats." No more textbooks or Star or syllabus stuff, just our class routine of warmup, learn stuff, practice, assessment...and I can't wait! So be ready for some new stuff next week (lots of writing about the graphs we now know how to create).
This weekend, please complete the following for homework:
Page 65: 7ab, 9a and....
Page 91: 13, 23abc, 29ab, 47
- For number 7a (p. 65)you are asked to describe the distribution--for now, I just want you to write a couple sentences describing what this graph tells you about sugar content (%) of different brands of breakfast cereals. You won't need any fancy statistical language here, this is just an intro to us writing about graphical displays
- For number 13 (page 91) you must show work to determine if there are outliers--you can't just create a boxplot on your calculator (you can use the boxplot on your calculator to check your answer, but show the math that proves these are outliers...)
- And remember check your answers in the back of the book!
- Your answer for #7a should include the following info--I wouldn't expect you to use the vocab in the back of the book (yet), so use this as your key
- The distribution of sugar content has two clusters of data
- One cluster is from 0-24(ish) % sugar (lower sugar amounts), and the other is from 40 to 56%(ish) sugar (higher sugar amounts)
- Generally, cereals tend to either have less than 24% sugar or more than 40% sugar,with few brands "in the middle"
And finally, here's Monday night's homework if you're feeling ambitious and want to get a head start:
Page 65: 9b (again, write a couple sentences describing what you see, no fancy vocab yet), 11ac, 17, 19a
Page 91: 3 (but use your calculator, don't do this by hand)
