And we actually calculated it and we got 24. What I want to do in this video is actually use this type of information, essentially these statistics we've calculated, to do some inferential statistics, to come to some type of conclusion, or maybe not to come to some type of conclusion. And what I want to do is just to put some context around these groups. We've just been dealing with them in the abstract right now. But you can imagine that these are kind of the results of some type of experiment. Let's say that I gave 3 different types of pills, or 3 different types of food, to people taking a test. And these are the scores on the test.
