5、inds of ability. Generally includes power, speed, stamina, agility and flexibility. Therefore, through the analysis of China agricultural university in 2010, 6290 students cervix result data, the relevant model is established using MATLAB statistic analysis theory, research the real status of the cu
6、rrent college students physical quality, the results of the study has a very important application value. First, use of descriptive statistics analysis method to a preliminary study on the cervix data. Second, analysis of variance on the height of 13 students of the college on a single factor analysis of variance and nonparametric analysis, judge the height of different college students have significant differences. In the study of the relationship between height and weight, use of MATLAN mad
