I’ve always been a bit skeptical of online education. I think I’m a good instructor. I know my subject extremely well, put a lot of time into preparing lectures, class activities and assignments. Having done some online classes, I have found it harder to gauge if students are confused or bored. Those hand-raises on goto…
“I teach statistics to people who don’t want to learn it.” This is my cocktail party response to people who ask what I do for a living. Even though I usually only teach one course a year, it is a quick way to answer the question and get back to drinking. Having faced up to…
Go to your local users group. If you don’t know if you have a local users group in your area, check the sascommunity.org page that lists bunches of them. There are six in California listed on their site and I heard of two others that started very recently that aren’t listed. LABSUG is the Los…
More about the Los Angeles Basin SAS Users Group (LABSUG) later, but I did want to mention one tangential point from the first presentation. It was on the Graphics Template Language (GTL). The first example was pretty cool, looking at the population pyramid by gender and year for the United States, then for Qatar at…
If you have a mad desire to do logistic regression with SAS On-Demand with SAS Enterprise Guide, here is a movie that shows how to do it. It is a .avi file so you may want to just download it and run it on your PC. Here is why the movie is not all that…
Let’s face it, 90% of everything on the Internet is crap. This is especially true when it comes to educational resources. So I cannot believe I did not come across these until now. Maybe they were just lost in the swamp of effluvia. I came across so many good resources lately that I am planning…
In fantasy land and fairy tales, there is this thing called equivalent groups. People are randomly assigned to a control group and a treatment group. Everyone in the treatment group receives the same treatment, for example, being sprinkled with exactly three teaspoons of fairy dust, and everyone in the control group does not….
Thank you, God, for St. Mary’s Catholic School, where someone back in the 1960’s decided that a speed-reading machine and programmed learning was a good idea. My father used to say that if they put words on toilet paper, I’d read it. I still read six or seven books a week, selected pretty much at…
I tried to find an easily comprehended explanation of the F-statistic for my students but I could not, so, here as a public service is mine. If you have some other pages you can recommend, please let me know. Okay, why ANOVA? Why not just do a t-test? Well, let’s say you have five groups….
Last month, I wrote about the steps to solving any statistics problem. A Pew Research Poll asked 1,201 adults “All in all, do you think affirmative action programs designed to increase the number of black and other minority students on campus are a good thing or a bad thing? Sixty percent said good, 30% said…
