The following assignment is to be turned in over the web at the class turn-in space,

https://catalyst.washington.edu/webtools/secure/esubmit/turnin.cgi?owner=bmck&id=106

Please submit the answers to all three questions below as a single, double-spaced file, using either text, html, microsoft word or Adobe Acrobat .pdf format.  Be sure your document has your name on it, and be sure it clearly labels the answers to questions one, two and three.

 
1. After the discussion in class on April 19, make any revisions you choose to in your statement of the important scientific questions to be answered by your analysis, and the statistical models that will be fit to help answer these questions.  Revise the last paragraph of your answer to each question from last week as necessary to report the important scientific question(s) your analysis this week will answer,  to define the statistical models that will be used in your attempt to answer these questions, and to explain the relationship between these two. Turn in only these revised last paragraphs in answer to this question.

 
2. Using the the crypt data now available on the class website assignments page, conduct an analysis aimed at answering the scientific questions you stated in #1.  Then write a double spaced, three-to-four page results section, reporting the results of the analysis.  This section should be  intended to be useful to the non-statistician who collected the data.  Be sure to include descriptive statistics and plots. 

 
3. Write a one-page (or less) statement of the conclusions you are able to draw from your analysis.  This page should contain a statement of any strengths or limitations you see in your analysis or in the collection of the data.
