This is a set of 2 probability models that students create and use to gather data in order to compare theoretical and experimental probability.
Uniform Probability- Students create a Magic 8 Cube from the net of a cube and choose 6 of the 20 outcomes given so the positive, negative, and no response outcomes are equally likely. Then, they are asked to determine the theoretical probability of each outcome. Once the Magic 8 Cube is taped together, students ask it yes/no questions and tally the results. They are asked to find the experimental probability and compare the results.
Non-uniform Probability- Groups of students create a spinner that is not equally likely and determine theoretical probability. The class performs the experiment, records the results, and determines the experimental probability. Groups are then asked to combine their data for more accurate results. Definitions/notes are included on the worksheet.
