Instructions, activities, and information about the StatPREP Little Apps.
Little Apps are tools for teaching and learning statistical concepts in a data-centric way. They are interactive web pages that display data and statistical graphics in standard web browsers.
There are two sets of links on this site:
Little App Activities document how instructors have used the Little Apps in their classes. Each activity pertains to a particular statistical concept or methodology. The activities were written by one or more StatPREP Hub leaders or participants. Each is available in HTML form as well as .docx
and .pdf
forms accessible from the HTML document.
The Little Apps themselves.
Each Little App is accessed through an ordinary web link (listed below) and is centered on a particular statistical methodology, technique, or graphic. Some of the Apps display techniques that will fit into just about any existing intro stats course.
Others are oriented to contemporary approaches to teaching statistics.
Still others implement topics can help instructors adopt to recent calls for change such as the GAISE recommendations about multivariate thinking and the American Statistical Association’s posture on p-values.
Each Little App is oriented around a graphical display of data with statistical annotations. Users can select the size of sample to draw at random from a “population” of the entire dataset. Every App shows each point in the sample.
