The results of educational examination are studied using the method of mathematical statistics. Also, the concentrated quantities,different quantities, probability and mathematical distribution,related coefficient,differentiality and pass rate of total examination results of different communities and each community are concretely computed and analysed. Meanwhile,the relationships among related coefficient differentiality and pass rate as well as the concrete range of value taking are discussed.The cause resulting in the deviation distribution is quantitatively analysed using the concentrated quantities and difference quantities. This process of the study and analysis is helpful to evaluate the qualities of any kind educational examination and the real ability as well as knowledge level of the examinees.
