Dear Experimenter,

Here's another set of frequently asked questions (FAQs) about doing design of experiments (DOE), plus alerts to timely information and free software updates. If you missed the previous DOE FAQ Alert, see below.

==> Tip: Get immediate answers to questions about DOE via the Search feature on the main menu of the Stat-Ease® web site. This not only pores over previous alerts, but also the wealth of technical publications posted throughout the site.

Feel free to forward this newsletter to your colleagues. They can subscribe by going to http://www.statease.com/doealertreg.html. If this newsletter prompts you to ask your own questions about DOE, please address them via mail to:[email protected].

For an assortment of appetizers to get this Alert off to a good start, see these new blogs at http://statsmadeeasy.net (beginning with the most recent one):

— Inverse transformation puts mileage comparisons on track
— Origin of 3.2% alcohol beer — an antidote for those dispirited by the Great Experiment
— Duck named DOE (pronounced "dewie")
— Brains for beer
— Sign for physics students still unclear on the concepts

(Correction to June FAQ Alert — John Hunter, the author of my fav blog — "Curious Cat" http://management.curiouscatblog.net/, is the son of the revered DOE expert Bill, one of the two unrelated Hunters (the other is Stu) who co-authored the landmark text "Statistics for Experimenters with George Box.)

Topics in the body text of this DOE FAQ Alert are headlined below. Given a plenitude of things worth alerting you too, I slacked off on FAQs and their answers. My excuse is taking some summer vacation that coincides with celebrating Independence. (Do you suppose I am referring to the separation of the United States from England; or could it be that I am celebrating the statistical assumption that one observation be independent of every other? Flip a coin!)

PS. Humorous observation by the late George Carlin on the widespread disrespect for people who do well with math:

"People love to admit they can't do math. But they will never admit to having a poor sense of humor."
