An application for creating, adjusting, and checking the suitability of data sets for courses that incorporate introductory statistical methods

CRAN status


The StatTeacherAssistant R package includes an interactive Shiny application, which is run locally on the user’s machine. It enables users to randomly generate data, make new versions of existing data through common adjustments (e.g., adding random normal noise and performing transformations), and check the suitability of the resulting data for statistical analyses. The app was designed to support educators in wide-ranging disciplines, with a particular focus on those teaching introductory statistical methods (descriptive and/or inferential) for data analysis.
