ANOVA and Japanese Methods Compared

Summary: The analysis of variation (ANOVA) method is widely used to calculate sigma within, between, and sigma total. Another method, the Japanese method of averages, is based on a method of statistical control charts. It is easily understood and can be developed on a computer using a Microsoft Excel sheet. A database developed by ANOVA and the Japanese method of averages will give similar calculated results using the same basic equation. It is easier to use the Japanese method of averages to calculate the sigma within, between, and total if the ANOVA method is not directly available.
