Abstract:

Teaching statistical concepts to students who do not have a strong quantitative background can be a challenging task. This research explores the potential of using interactive visualization tools to help students in learning statistical concepts. The following examples will demonstrate the use of a visualization tool in illustrating specific concepts commonly encountered in biostatistics courses: a java-based interactive heat map program developed by the authors illustrates the concept of "overlay" in teaching ANOVA; a graphical interface, Xcelsius, illustrates the teaching of linear models through a dashboard of interactive dials; a commercial visualization tool, Tableau, illustrates the analytic issues involved in the analysis of longitudinal data through the use of multiple panels, colors, shapes, and sizes.
