LOCUS assessments
The Levels of Conceptual Understanding in Statistics (LOCUS) project developed a family of tests for measuring statistics knowledge that are freely available online. The aim of the LOCUS project (PI: Tim Jacobbe) was to develop statistics tests that measured conceptual—rather than procedural—knowledge. I joined this project as a graduate student and have continued to use these assessments and document their validity evidence for use with different populations.
