Final Project

Due: TBD: Last day of class/finals

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.

Approval deadline: TBD

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.
