Discussion of Variance Analysis: Double Factors-no Repeated Variance Analysis

The basic principle and the significance of variance analysis method are discussed. Variance analysis is defined as that total variance, which is first decomposed into each variance component. Then, analysis, judgment, and appropriate conclusion are made through the use of significance test method. Double factor variance analysis method is introduced and explained Through the examples, and questions raised by students are answered, such as how to judge the plurality in testing the components of a sample using several different methods by different investors and why every kind of analytical method are repeated several times, and how to judge if there is significant difference in results between different analysis methods and investors.
