Step 1
The result of ANOVA :
For a pooled SD , we calculate the difference between each group value and its respective group mean, square those differences, add them all up (for all groups) , which corresponds to SS , then we divide SS by degrees of freedom to get MS
In ANOVA , the pooled SD is the square root of MSError
