Summary of project

In the seminal work of Lord and Novick, Statistical Theories of Mental Test Scores (1968), the idea of item sampling is put forth. Though Johnson and Lord (1958) already introduced the idea a decade before, it seems that it has not gained much popularity in neither literature nor applications since. One of the explanations for the lack of attention in this area might be the use of generalized symmetric means (gsm) (Lord and Novick, p. 238), which are a highly complicated set of expressions limiting the usability of the whole procedure.
However, responses gathered through randomly selected items hold several desirable properties for which other procedures than the one suggested by Lord and Novick can be employed. Purpose of this proposal is to develop and apply such alternative procedures, and thus to extend item sampling theory.
