Revised STA429/1007 Assignment 11

Quiz on Thursday Dec. 6th


Using the potato data presented in Handouts 10 and 11, conduct a randomization test for any mean difference among the 6 experimental conditions. This is analogous to the initial (overall) F-test, and in fact I would like you to use that test statistic in your test, computing it on 5,000 random permutations of the data. Your objective will to get a randomization p-value, consisting of the proportion of F statistics from the randomly shuffled data that equal or exceed the F=15.05 that we got from both SAS and R.

Feel free to borrow as much of my code as you like. It's available here.

If you are having trouble reading the data, try making the data file end with .txt

The "quiz" will be to circle the randomization p-value and hand in the printout.
