Anyway, I'll try to pay attention while it's going off. To test whether the results could be explained by random chance, she created the table below, which summarizes the results of 1,000 re-randomizations of the data, with differences between medians rounded to the nearest five minutes. What is going on over here? You might say, well, look, she got her result that she wanted to get. She sees this data seems to confirm that bus A gets her to work faster. What's all this other business with re-randomizations she's doing? Well, the important thing to realize is, and she realizes this, is that she might have just gotten this data that I underlined by random chance.
