| Abstract: | This paper tests whether the populations of examination record reconcile the normal distribution in detail,in the light of the examination record of the course "probability theory & mathematical statistics" from recent three years,dividing into six terms,by applying the testing method of skewness and kurtosis.A histogram is drawn.The reasons for the examination records change normality and the instructable policy which should be taken are analysed in depth.The statistical results take wide generality. |
