Nowadays factor analysis has been extended greatly, and one of its applications is to analysis the attributes which are
not measurable directly. While the response variable has a Bernoulli distribution, using factor analysis method for
continuous quantities leads to invalid and misleading results. Factor analysis for Bernoulli response variable base on
Logit model is developed in this paper and its applications have been explained for read data from a research project
about the high school mathematics textbooks in Iran.
