Re-quiz tomorrow · Jan 27, 02:29 PM
I’ll quiz today’s material again tomorrow. I’ve prepared an answer key which I need to scan and upload. It will be available after 3:30.
To prepare, most of you should focus on two things:
1. picking up easy points like “defining variables” and “answering in context.” I graded the first question as follows:
| Define variables | Calculate | Check conditions and assumptions | Answer in context | TOTAL |
|---|---|---|---|---|
| 1 | 4 | 1 | 2 | 8 |
2. recognizing the difference between rescaling one random variable and combining random variables that happen to have the same mean and standard deviation.

AP Stats: Simulation data · Nov 2, 04:13 PM
I’m uploading both a simulated data set and the spreadsheet itself. You only need the former. The latter is for geeky or the brown-nosed.

My outline · Oct 22, 04:35 PM
Here’s the outline I showed you today. I exported it as text, opened it in Word, and changed the outlining format from 1.1.1.1.1 (Yuck!) to I.a)i). I also edited the text a little because the standard outline format requires that you be a little more explicit.

The “relationships” — that’s a term used by the MindMap software — are converted to text following the words “See also.” I italicized those parts for emphasis.
By the way, adding outline codes was a little tedious, but maybe not as bad as you might think. If you place the cursor before the lines of text one at a time and click the outline button, Word figures out what you are trying to do and converts the plain text “1.1” into an outline code. Though it looks the same as the plain text, you can then change the outlining format without needing to retype anything.
