There were two examples used this week that involved a model of a random process representing a real world phenomena and data generated from the model. Duck Pond Game: In the carnival Duck Pond example, a model was built and data generated to answer questions about the context (how many prizes should the booth owner buy, how many prizes do we expect each player to win?). Schoolopoly: In the Schoolopoly example, there were three models built (but hidden) that represented probability distributions for three different dice. Data was generated from these models of unknown distributions to allow students to make an inference about the structure of the models
