In this data file, you’ll be able to demonstrate what the Normal distributions of men’s and women’s heights look like — and spoiler alert, it’s not bimodal. The heights aren’t distinct enough for that. This could take 5 minutes in class for a discussion. With a GeoGebra file, download it first, open GeoGebra, then go to the open existing file from computer option.
In this demonstration, students can play around with rolling dice to see a sampling distribution at various sample size n. With CODAP files, download them to your computer, then open the local file in CODAP. This should take 15–30 minutes depending on how proficient your students are with CODAP.
In this demonstration, students can play around with a regression line to see its residuals change. GeoGebra will automatically show the calculation of r-squared. This should take 10–15 minutes.
