The STAT-ATTIC Website: Links to Statistics Applets for Introductory Courses
No TL;DR found
Abstract
Statistics instructors are increasingly using stand-alone applets to illustrate statistics concepts to students. There are hundreds of applets available on the web, but locating a quality applet to serve a particular purpose can be time consuming. This paper presents the STAT-ATTIC (STATistics Applets for Teaching Topics in Introductory Courses) website, located at http://sapphire.indstate.edu/~stat-attic/index.php, as a tool for locating statistics applets for a particular pedagogical purpose. The site has links, with descriptions, to approximately 600 publicly available applets on topics commonly taught in introductory courses, including graphical displays, descriptive statistics, probability concepts, random variables, sampling, confidence intervals, hypothesis tests, regression, ANOVA and chi-square tests. Within each broad topic, applets are organized by intended purpose; for example, applets intended to illustrate properties or behavior are shown separately from those that calculate statistics or perform tests. Advantages of the database over other statistics resources are presented, along with the process that was used to identify and select applets for the site. Lastly, the structure and functionality of the database, including the ability to search and rate or comment on applets, are also discussed.
