Abstract:
In this article the estimation of usefulness of multiple choice tasks was based on logical statistical procedures concerning the structure of data. Susceptibility of tasks on qualitative and quantitative standarisation procedures was connected with their suitability and reliability. Four relations were distinguished: (1) relation of comparing, (2) relation of similarity, (3) relation of domination, (4) relation of preference. Each relation was connected with different aspect of tasks casiness.
