It seems like a reasonable critique. The suggestion is to include such ideas as people are taking introductory statistics which isn’t inappropriate. I wouldn’t suggest forcing students to code up their own simulations from scratch, but creating a framework where students can plug in various formula for each population, attach a statistical test, and then run various simulations could do quite a bit. However, what kinds of formula students are told to plug in are important if every formula is producing bell curves then that’s a failure to educate people. 50d6 vs 50d6 + 1 is easy enough you can include 1d2 * 50 + 50d6 for a 2 tailed distribution, but also significantly different distributions which then fail various tests etc.

I’ve seen people correctly remember the formula for statistical tests from memory and then wildly misapply them. That seems like focusing on the wrong things in an age when such information is at everyone’s fingertips, but understanding of what that information means isn’t.
