Rguroo tools for teaching proportion inference using the binomial exact and the normal-theory methods

Most students have a better conceptual understanding of counts than proportions.

In this webinar, Dr. Mori Jamshidian of California State University, Fullerton, will show how inference about a population proportion can be taught using sample counts rather than the commonly used sample proportion. This will then lead us to introduce the binomial exact method.

Dr. Jamshidian will also demonstrate Rguroo’s simulation and graphical tools that aid in teaching sampling distribution of sample proportions and show Rguroo’s functions for applying the large sample normal-theory methods.

Using Rguroo you can upload the above RGR files and recreate all data from the webinar, just like a student would after an interactive lecture.
