Biological Data Analysis: Homework 10

Due Tuesday, Dec. 6


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 two 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 test of goodness-of-fit" and one whose answer is "paired t-test." Your third question should have your very favorite statistical test as the answer. 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. You don't need to turn in anything for this question. Look at the questions on the first set of practice questions and second set of practice questionsfor the final exam, and see if there are any that you don't understand. Come to class on Thursday prepared to tell me which of the practice questions you'd like me to explain in class. You may want to avoid looking at the third set of practice questions until after the last class, to see if anything we review helps you answer the questions better when you see them for the first time.
