I know a lot of you in the physics department take the log of 0 and call it negative infinity. We’re in the math department here, and we do not do such horrible things.

So this is how to calculate least significant differences…but please don’t ever use it in the real world. Use Tukey’s. If you tell people that I told you to use LSD in grad school, I’ll go to jail.

In this class, we’ll be happy if we get R-squared values of over 0.98. But if you’re a sociology researcher, you’d be jumping for joy if you got an R-squared that was greater than 0.5.

I have never heard someone use the word “urn” outside of probability classes. And considering that the only thing that anyone puts in urns is the ashes of dead people, it’s weird that we’re talking about the probability of pulling balls out of them. But I guess that’s less disturbing than asking about the probability of sticking your hand into an urn and pulling out a clump of ashes that contains grandma’s hand.
