The lesson I learned from previous exercise which still cannot be fix was How to analyze the data. Statistical data analysis, it is necessary to choose a right statistical models and truly understanding the different types of variable in statistics. By using the statistical models such as ANOVA, ANCOVA, MANOVA and statistical technique such as typically one-way ANOVA, two-way ANOVA, and three-way ANOVA We must considering the Independent variable and Dependent variable example as below ;
