摘要：One of the most important sensitive stages in research process is the design and
outline of measurement tool. Effective measurement tools are those which are
both valid and reliable. Also, in many managerial researches, the researchers
utilize the specific models which are used in the previous researches, or design
and test new models, using the modern knowledge. It is clear that the effective
research model is a model which has enough validity. In order to determine the
validity of researches measurement tools and models, numerous techniques are
used such as the judgments of the experts, correlation test, multi traits-multi
scale matrix, and multi-factor analysis. The practical suggestion of this survey
is to utilize discriminate analysis technique in order to study and measure the
validity of simultaneous managerial research models
