This module was used in the majors introductory non-lab biology course at the end of the semester as a culminating experience to track their Excel and data interpretation skills. The purpose of this course is to introduce potential biology majors to the process of science and to understand that all the science information they read in their textbooks comes from people doing work and analyzing information. The class meets for 90 minutes twice a week. The module was done in class with class discussions of the results interspersed throughout the module.
