This module was implemented in a 1st year course (lab) designed for majors, but is also an option for non-majors to fulfill general education requirements. Before we started the lab, a PPT on linear regression and basic statistical analyses in Excel was presented (that PPT is available in this Collection). I then gave this brief PPT on phenology and I introduced the module. The entire module fit in a single 4 hour lab period with most students taking 3.5 hours to finish.
