# Biological Data Analysis: Homework 6

## Due Tuesday, Oct. 15

**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. **Perform a one-way anova on the data you collected for homework 3, using the spreadsheet linked on the one-way anova page. Report the F-statistic, the P-value, and how the variance is partitioned.

**2. **Plot a bar graph of your data, with the means arranged from smallest to largest. Show the results of the Tukey-Kramer test on the graph.

**3. **Perform a one-way anova on the data you collected for homework 4, using SAS. Print your SAS program and the output (the .lst file). If you didn't get a .lst file, or if your P-value was different from the spreadsheet results, print the .log file. If you couldn't get SAS to work last time, be sure to look at the introduction to SAS and the sample program on the one-way anova page, and get an early start on this so you can e-mail me if you have problems.
