Objectives Students learn to use a Monte-Carlo method to collect data. Students learn about simple, random samples. Students develop hypotheses about how to assure samples are representative. Students learn that randomized, larger, higher-resolution samples yield more accurate results. Students learn about the value of high-fidelity models.
Procedures Inflate the globe, then start tossing it to others in the room.
As participants catch the ball, they note whether a designated finger falls on water or on land. How many tosses to make to get an accurate answer or to simplify the arithmetic. You may test each protocol to see how the results vary when the process is not random. Once protocols are established, tally the number of times the sample selects a point on land or on water. Compute the ratio of land to water.
