In today's class (March 21) I mentioned how men and women have different weight distributions so that if we combine them, the distribution looks bimodal (two peaks). This article by statisticians at Johns Hopkins has a good analysis of when two distributions combine into two peaks and when they combine into one peak. It turns out the example in class would combine to one peak. The "living" histogram pictures in the article are also worth looking at.
This Slate article provides a very important reason why the confusion of the inverse is important (a topic we covered in Section 4.5).
This link is the Mathematica file I showed in class simulating the distribution of the 59 (alive) Hunger games winners into their respective districts. To view it, you must download it on your computer and use Mathematica. To make the simulator run, put the cursor on top of the program (the bit that goes from count=0 all the way down to N[1-count/n]) and click Shift + Enter.
Bill Barnwell wrote a very good football article using z-scores to compare football offenses (and defenses) across eras. You can find the article here.
Textbook
Elementary Statistics (12th edition) by Mario F. Triola.
Topics to be covered
In this class we'll give an introduction to probability and statistics. We'll cover Chapters 1 through 8 of the textbook and Chapter 10. If there's time we'll cover more.Grading
The course grade will be based on:
Homework 10%,
Midterm 1 20%,
Midterm 2 20%,
Midterm 3 20%
Final Exam 30%.
There will be written homework due roughly every week. Collaboration in the homework is permitted, but you are not allowed to copy someone else's work. The solutions must be written individually. The homeworks will be posted in the Announcements section and also on this link.
The homework problems will be designed to reinforce ideas and develop your logical reasoning abilities. The numerical grade given on a single assignment is not important for your grade (it is mainly to give you feedback on how you're doing). As long as HW is consistently done and of reasonable quality you will get the full benefit of this 10% of your grade. Late HW will NOT be accepted.
