Mean process analysis

   Since only the mean process variable from the first layer and the linear correlation analysis of variance test, and therefore the mean two or more than two factors factor analysis of variance analysis and the results of the same single factor, except that the descriptive statistics, descriptive statistics are multifactorial statistics for each cross-category

One-sample T-test

Conditions u t test and inspection

⑴. Samples from normal, or near normal population overall

⑵ sample population variance is equal to two, i.e., having homogeneity of variance (at the time of practical application, such as a slight deviation from the above-described conditions, the result will not be much affected)

⑶ two samples shall be independent of each other. (Depending on the comparison, one-sample t-test is divided into t-test, paired t-test and two independent samples t-test)

That one-sample test work test whether there are significant differences between population means of a variable and a specified value. If it is a large-sample test sample, called U test textbook on statistics, the use of statistics U obey normal Fenbu as a test statistic. If it is a small sample and the sample normal distribution, subject to the use of: (system weight distribution for single sample T test; otherwise, take .T test the robustness of the non-parametric test (Robust) is better, if the sample distribution deviates from the normal distribution less severe, may also have T-test
