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?

Having received email from readers who believe that Spirit Lake: The Game is exploitative or disrespectful of Native Americans, I asked the individual who designed the Level 5 problem shown in my blog post of November 18 to respond in a guest post. What I Hope to Accomplish with a Math Game for Native American…
The past couple of weeks, I’ve been hearing my friends from Turtle Mountain and Spirit Lake talk about the election in North Dakota. I was particularly interested because this was the one election that Nate Silver predicted incorrectly. He had Heitkamp down by 3.9 percent, and yet she won. I have no idea how Silver’s…
On the long list of things that irritate me, few score higher than people who have “an idea” for a start-up and are then going to find “you know, people” to code it for them. I was cheered up when I ran across this youtube video where AngelList founder Naval Ravikant advises the winners of…
