Mixed kernel empirical distribution displayed with individual "sand" layers.
Mixed kernel empirical distribution displayed with individual "sand" layers.[/caption]Professor of Mathematics Todd Lee presented a paper at the Ninth International Conference On Teaching Statistics held in Flagstaff, Ariz., July 13-18. The paper, which he co-wrote with N.C. State University Professor Hollylynne Lee, was invited in the session for “Innovation and reform in teaching probability within statistics: Modeling distributions to connect chance processes, data production, and data distributions”.

Abstract: This paper is an expository on searching for intuitive visualizations of empirical probability distributions. The visualizations use the granular density metaphor for probability density functions (Lee & Lee, 2009) to provide a way for students to build from equiprobable intuitions of probability to standard discrete and continuous distributions. The visualizations dynamically link the sampling process with the formation of an empirical distribution, while remaining true to the granular density metaphor for both the empirical and theoretical density functions. We present and discuss several examples along with conceptual and mathematical ideas that support use of these visualizations.

Lee co-chairs working research group at PME-NA /u/news/2007/11/01/lee-co-chairs-working-research-group-at-pme-na/ Thu, 01 Nov 2007 19:52:00 +0000 /u/news/2007/11/01/lee-co-chairs-working-research-group-at-pme-na/ Todd Lee, associate professor of mathematics, co-chaired the Working Group For Learning To Reason Probabilistically Through Experiments And Simulations at the annual conference for the North American chapter of the International Group for the Psychology of Mathematics Education. This working group has been active in the PME-NA since 1998, and has resulted in several waves of research in different lensed approaches to the learning of probability in k-12 and college students.
