WHAT IS IT?
A Fathom 2 classroom activity that could be adapted for work in groups or individual project depending on the experience of the students in data analysis asks the question: Is this reasonable?
Through simulation, students investigate how likely, or unlikely, it is to obtain results similar to those presented in a hypothesized study. Multiple samples and measures are then collected using Fathom. The activity concludes by discussing how the original experimental design can be improved.
