Abstract:
|
A fundamental property of measure, which is called additivity, is discussed first and then, with subjecting to the additivity, a new measure is defined for measuring abilities. The fundamental properties of this newly-defined ability measure are explored with mathematical proofs. This paper shows that shared ability and unique ability are measurable with this newly-defined measure. Also, the ability measure with subscales and partial credits are studied.
