This project was designed to be used in a freshman calculus class whose students had already been introduced to logistic functions and basic data modeling techniques. It need not be limited to such an audience, however; it has also been implemented in a topics in mathematics class for college upperclassmen. Originally intended to be presented in two classroom periods with outside-of-class work after each, the module could also be issued entirely as an out-of-class project, with students reading the background information that would otherwise be presented in class.
