Study 22 review exam 3 flashcards from a repeated measure and independent measure study both produced if the null h is true, what value is expected on average. The true score theory is a good simple model for measurement, but it may not always be an accurate reflection of reality in particular, it assumes that any observation is composed of the true value plus some random error value.
