Biological Data Analysis: Homework 10

Due Tuesday, December 4



You must type this and all other homework assignments. Do not e-mail the assignment to me; turn it in early (at 322 Wolf) for a foreseeable absence, or turn it in late after an unexpected absence from class.

1. Write three exam questions, in the same style as on the study guides and the first three exams. The questions must describe an experiment, then ask "Which test should you use?" The answers to your first two questions are given below, next to your birthday; for example, if you were born on the 6th of a month, you must write one question whose answer is "exact binomial test" and one whose answer is "paired t-test." Your third question can have any of these answers. Be sure to include the answer to each question. If you're writing about your area of research, be sure to give enough detail that all of your classmates would understand the question.

2. Take the first practice exam. Write down the questions you find difficult, so that you can ask me about them in class on Tuesday. We will spend Tuesday's class going over the answers to the first practice exam, starting with the ones you ask me about.

You should NOT turn in anything for this question.

3. (Optional) Go to the course evaluations page and enter your evaluation for this course. There are a lot of questions that are somewhat redundant, so only answer the ones you want to. This will help me improve the class next year, and I greatly appreciate it.

You should NOT turn in anything for this question.

4. (Also optional) Go to RateMyProfessors.com and rate me. This will help future students know whether to take this class, and they will greatly appreciate it.

You should NOT turn in anything for this question.
