I was supposed to be teaching statistics to undergraduate Fine Arts majors this semester but I’m going to Santiago to open a Latin American office for 7 Generation Games instead. I’m a bit disappointed because even though when I was younger and got asked at cocktail parties what I did for a living, I would…
In a previous post, I asked what you would do if one person’s score changed your results? Would you throw them out? Leave them in? Does it depend on whether they support your hypothesis or not? A few people suggested collecting more data and I completely agree with their very valid points that if one…
This is a hypothetical question, but it could easily happen. Let me give you a real example.

Last post, I talked about bricolage, the fine art of throwing random stuff together to make something useful. This is something of a philosophy of life for me. Seems rambling but it’s not … Over 30 years ago, I was the first American to win the world judo championships. A few years ago, I co-authored…
Once every year, I teach an actual course, not a workshop or professional development, but a class with 20 – 40 students.

So, after three posts of recoding, creating scales, checking reliability and distributional assumptions we have arrived at MANOVA. If you skipped those three posts, feel shame at trying to take shortcuts, go back and read them. Before we dive into coding, let’s take a look at some basic background on MANOVA.
