Abstract:Analysis of variance is an effective method in mathematical statistics.Based on analysis of variance,in this paper we studied the dual factors test from non-repeated dual factors and repeated dual factors.And through the structure of the statistic,discussed whether two factors are remarkable to influence of the test result.This paper endeavors to make us comprehend further more about the variance analysis of the duplicated experiment on the dual-factor by introducing the principle of it and the application of it in the manufacturing,and by using the SPSS to do the dual factors analysis of variance.
