Collecting Pens (Continued)

Activity Overview

In this activity, students learn how to instruct the calculator to collect and organize the results from several trials of a simulation designed to find out how many boxes of cereals a customer would have to buy to collect all six color pens. Students enter a prewritten program, analyze the results of the simulation from the summary statistics and statistical plots.
