And collected all my data.

Book Review: Strange Curves, Counting Rabbits, and other Mathematical Explorations
By Peter Flom, January 17, 2010 3:30 pm
Strange Curves, Counting Rabbits and other Mathematical Explorations is an excellent popular math book for the right audience. I had a lot of fun reading it, and will probably re-read at some point.
What is the audience for Strange Curves, Counting Rabbits and other Mathematical Explorations?
This is a book of recreational mathematics, but it is relatively serious. Several of the chapters have some calculus, one has a bit of simple matrix algebra. So, if you are reading this on your own, it’s probably best if you had at least one course in calculus at some point – even if you don’t remember it very well. So, that’s one audience.

It was invented by William Sealy Gosset, who wrote under the pseudonym “student” to avoid detection by his employer (the Guinness Brewing Company). Guinness prohibited publications by employees, because another employee had divulged trade secrets in writing.
There are also one-sample versions of a the t-test, to tell if a sample has a mean equal to some fixed value, but these are relatively little used. Continue reading 'The t-test'»
