This paper is to help a teacher carry out the test about whether or not his teaching method is more effective, compared with existing method or other teacher's method.
In this paper, the followings are shown :
1. We derived a probability density function of multivariate normal distribution and arranged 1-dimensional, 2-dimensional, and 3-dimensional normal distribution.
2. We described the theory on student's t-distribution and F-distribution, the mean, and the variance.
3. We described t-test theory used in comparison and analysis of one sample mean or two sample means, and F-test theory used in comparison and analysis of several means.
4. Finally, we showed t-test and F-test with the example and described the method of comparison and analysis using SAS.
