An Early Review of G. Rasch: Probabilistic Models for Some Intelligence and Attainment Tests, Danmarks Paedagogiske Institut, 1960. 184 pages. Danish kroner 20.
Georg Rasch is a mathematical statistician who does not only criticize the use of classical statistics for behavioral science problems due to his own (bad) experience; he goes on and formulates new models.
It has always been debated whether the results of a psychological experiment tell something about the persons tested or about the experiment. Rasch has ingeniously solved this problem replacing the set of stimuli with a parameter (called σ) and the set of personal factors also with a parameter (called θ). These parameters can be estimated; they may be as well one- as multidimensional.
(... A mathematical description of "Rasch's Measurement-model" ...)
We face here an important methodological improvement with analogies to other behavioral sciences than the psychological (children's reading ability has been the base for the model development). Certain extensions must be made, however, if the model should be used directly for measurement of other phenomena.
