Summary This article presents an activity that engages students in considering characteristics of a random sequence, in this case, a randomly generated playlist of songs using the iPod shuffle feature. Students examine simulated sequences of randomly generated songs from a small music library in order to identify characteristics that are used to develop rules that they then apply to judge whether three suspicious lists are likely to be nonrandom.
