forum 9: week of 12 March: Fisher and the design of experiments

Fragment of a discussion from Course talk:Phil440A

Unless I have access to the analysis of variance (ANOVA) table, I cannot comment on the last paragraph (pertaining to what the results indicated, or the conclusion that was drawn from the experiment). Also, I should mention that ANOVA (e.g., see http://www.stat.columbia.edu/~gelman/research/unpublished/econanova.pdf) is a separate technique in itself, distinct from the type of significance tests that Fisher introduced in Chapter 2 of his book (i.e., the reading for this past week). To answer your question, page 248 of the Boeing Advanced Quality System Tools document does not satisfy my concept of significance test methods insofar as it not relating at all to the significance test introduced in my presentation earlier this week. I hope this helps. If you have any more questions pertaining to the example you gave me in the Boeing Advanced Quality System Tools document, then I suggest we do not communicate on this forum but in other ways that will not disturb the focus of the discussions in this course.
