Unit 10: Hypothesis Tests
Text reading and homework:
Read chapter 26 of FPP and do the following review exercises:
Chapter 26 (pages 495-500): 2, 3, 4, 5, 7
"Baby heart risk for hairdressers and nail bar workers?" on the
BBC News Health website, 17 July 2012.
Possible essay questions:
- Why did the survey use such large samples?
- The difference in risk for mothers was reported explicitly,
while the difference for fathers was not. Why do you think
the writer chose to phrase it that way?
Writing Assignment (Midterm Project II):
For this unit you will take the
results of the
online survey taken by the members of the class and write the Statement
of the Problem, Method and Results sections in the style of a final
project (as described in the guidelines).
(The Background section is to be omitted here, but it is needed in the
final project.) The Statement of the Problem is just that: the questions
you would like
to answer using some of the survey results (just the ones relevant to
your question, of course). The Method section should describe the
online survey itself, the statistical tests you have decided to use
to analyze the data, and why you chose them. The Results should give,
clearly, concisely and objectively, the numbers (averages, slopes of
regression lines, etc.) and perhaps a few graphs (most of those would
appear only in the appendix, but a few illustrative ones can go here)
that result from your analysis. You should not state definitive
conclusions -- they would go into the unwritten Discussion/Conclusions
section. These three sections should take a total 2-5 pages.
