Mites and Wilt Disease - Using Simulation to Examine a 2 x 2 Table

Tuesday, January 26th, 20102:30 pm – 3:00 pm ET

Presented by: Alicia Gram, Smith College


This webinar will describe an activity that uses data collected from an experiment looking at the relationship between two categorical variables: Whether a cotton plant was exposed to spider mites; and did the plant contract Wilt disease? The activity uses randomization to explore whether there is a difference between the occurrence of the disease with and without the mites. The webinar will include a discussion of the learning goals of the activity, followed by an implementation of the activity then suggestions for assessment. The implementation first uses a physical simulation, then a simulation using technology.
