S5E19 Item Response Theory, Q.E.D.


In this week’s episode Patrick and Greg provide an introduction to the Item Response Theory model: what it is, how it relates to traditional factor analysis, and how this modem approach improves upon some of the limitations of classical test theory.  Along the way they also mention weinerness, memorizing Latin for punishment, eggszampke, in ether words, ITR, switching a and b, I’m not defensive – you are, why biostatisticians hate us (page 3 subsection 8), binary babble, EAPs and MAPs, computer adaptive  testing on the playground, Bob’s your uncle, and the liberal arts mic drop.
