 、陈述原假设H<sub>0</sub>和备择假设H<sub>1</sub>，确定进行检验的显著性水平α；
-State H<sub>0</sub> and H<sub>1</sub>.Determine the level of significance α.
+ * State H<sub>0</sub> and H<sub>1</sub>.Determine the level of significance α.
 、确定检验的方向性，需要注意的是ANOVA检验总是**单尾检验**；
-To determine the directionality of the test. It should be noted that the ANOVA test is always a single tail test.
+ * Determine the directionality of the test. Notice: the ANOVA test is always a **single tail test**.
 、指出检验的自由度df，注意在ANOVA检验中有两个自由度，分别是组间变异的自由度（k-1）和组内变异的自由度（N-k），其中k为设置水平数，N为总的样本容量；
-It is noted that there are two degrees of freedom in the ANOVA test, namely the degree of freedom of inter-group variation (k-1) and the degree of freedom of intra-group variation (N-k), where k is the number of setting levels and N is the total sample capacity.
-、查表找出临界F统计量，需要用到的有组间自由度、组内自由度以及显著性水平α，知道这三个值即可查表找出临界F统计量的值；
+ *  Indicate the degree of freedom of the test. Notice: there are two degrees of freedom in the ANOVA test, namely the degree of freedom of inter-group variation (k-1) and the degree of freedom of intra-group variation (N-k), where k is the number of setting levels and N is the total sample capacity.
-Use the α of degrees of freedom between groups, degrees of freedom within the group, and significance level to look up the table to find out the value of the critical F-statistic.
+、根据组间自由度、组内自由度以及显著性水平α，查表找出临界F统计量的值；
+ * Find the critical F statistic by looking up the table according to inter-group degrees of freedom, intra-group degrees of freedom and significance level α.
 、对于样本计算F统计量的值，画出如下图所示的方差分析表

-Calculate the F-value of your sampple, and draw the ANOVA table as shown in the figure above.
+ * Calculate the F value of your sample, and draw the ANOVA table as shown in the figure above.
-、比较计算得出的F值和临界F值，如果F<F<sub>crit</sub>，则接受原假设H<sub>0</sub>，如果F<F<sub>crit</sub>，则拒绝H<sub>0</sub>，接受备择假设H<sub>1</sub>；
+、比较计算得出的F值和临界F值，如果F<F<sub>crit</sub>，则接受原假设H<sub>0</sub>，如果F>F<sub>crit</sub>，则拒绝H<sub>0</sub>，接受备择假设H<sub>1</sub>；
-Compare the calculated F-value with the critical F-value.If F-obs < F-crit，then accept the null hyphothesis; if not, then refuse it and accept the alternative hyphothesis.
+ * Compare the calculated F value with the critical F value.If F<sub>obs</sub> < F<sub>crit</sub>，then accept the null hypothesis; if not, then refuse it and accept the alternative hypothesis.
 、进行事后检验。
-Carry out the postmortem.
+ * Carry out the post hoc test.
