How Random is "Shuffle Mode"?

Shuffle mode is random, right? The lesson simulates playing a music list in shuffle mode through two different players. Using the number of times a song is played first in the list, pupils determine whether the players are fair—or truly random. Scholars view the data using different methods to decide which one makes it easier to analyze.
