## Homework Assignments

Homework 0 (optional): Assigned 6/1/05, due Monday 6/6/05 (in class) - "Statistics in the News - Estimation of Shredded Documents," good for 1 point on final course grade.   Problem: Using this 12/23/04 news story as your source for data, estimate the equivalent building size needed to store the destroyed documents. I.e., the overall building FOOTPRINT DIMENSION and NUMBER OF FLOORS. Use a building with which we are familiar, e.g., Wleder Hall, the Eiffle Tower, etc. Try to keep it simple (convert everything to linear meters, use rectangular buildings, etc.)   To receive credit, your analysis must: (1) summarize the data for each department; (2) state your assumptions, with an explanation for the data presentation technique you chose; (3) Draw a floorplan layout to validate your claim; (4) paper must be NO MORE THAN 2 PAGES!

Optional Problem: Get some data on your internet browser favorites/bookmarks! To receive credit, your analysis must: (1) summarize the data for the counts of numbers of level of folder/bookmarks, and bookmarks; (2) paper must be NO MORE THAN 1 PAGE! Additional help and information is HERE.

## Final Project

 Due: Last day of finals TBD for graduating seniors TBD for non-graduating students

Within this project you must demonstrate five different aspects of a statistical study. The project should be 5-10 pages in length. You may use either an observational study or a designed experiment. I must approve your topic of research before you begin.

1. Pose a question that you can answer with data (which must be approved by me).

2. Explain how you will select the data or design the experiment to gather the data. Provide your rationale for the choices.

3. Include your data (in an appendix) and provide an appropriate graphical display. The descriptive methods you use should relate to the research question you have chosen to answer.

4. Perform some statistical inference on your data and provide reasoning for your choice of methods. You should summarize your findings, relating them to your research question.

5. Summarize what you have done in layman's terms, so that a person without any statistical knowledge would understand your findings and how you obtained them.
