Statistics Concept Inventory

The Statistics Concept Inventory (SCI) is a multiple choice assessment tool designed for introductory statistics courses.

The SCI is designed to be in similar format to the Force Concept Inventory, which has been successful in assessing student understanding of Newtonian Mechanics and transforming teaching to improve understanding. The scores and gains (from pre to post) are similar to those found on early testing of the FCI in classes which use the traditional lecture format.

The SCI is divided into the sub-tests Descriptive, Probability, Inferential, and Graphical based on the results of factor analysis. Each category has around 9 questions.
