Welcome to my stats and psychometrics website — I am curating a resource for students who are learning about the principles of inferential statistics and the field of psychometrics (measurement assumptions inference rests) - I hope you find this useful.
Building inference from first principles — what averaging buys you, how the standard inferential tests actually work, when their assumptions hold, and how to plan a study honestly.
A companion track on what is actually being measured — the assumptions every Likert scale silently makes, the reliability of psychological measurement, and what attenuation does to the inferences that follow.
