P.Mean: Glossary for my
second book (created 20100811, updated 20130802).

As I mentioned in an earlier webpage, I am
talking to some publishers about writing a second book. Here's a tentative
glossary for that book. I'm only including the terms in the glossary for now,
but will eventually add definitions.
 Alpha level. Every statistical test has the possibility of making a Type I error or a Type II error. Alpha is the probability that your statistical test will make a Type I error. Typically, you select a test that has a small probability of a Type I error (e.g., alpha=5%). Sometimes, you are willing to tolerate a larger Type I error, if Type II errors are more serious, and will set alpha to 10% or even higher. Sometimes, Type I errors are very serious and you will require a much smaller probability for the Type I error (e.g., alpha=1%).
