R is a free (yep, FREE) software environment for statistical computing. Although that description might sound intimidating, do not let it put you off. I love R. No, I REALLY mean it. Since I’ve been using R, my statistical life has become a dream. The beauty of R is that you can do almost ANYTHING you want to with it (it doesn’t make coffee, although a package might be available for that someday; hey, I can dream, can’t I?). Continue reading

Although it would be great to get students to go off and collect lots of different data sets, each suitable for exploring a particular statistical test, a quicker alternative is perhaps to provide the data via computational simulation. Then, students can quickly explore new data sets in interesting ways. Continue reading
