A Data Science Project- Part 3: Hypothesis testing and ANOVA

This post is in continuation of A Data Science project series. In this post, We will use ANOVA test whenever we need to check if two or more groups are different from each other or not. i.e. let’s say there are four races in a school – White, Hispanic, Black and Indian. Now school management wants to know if the marks scored by these races are statistically different or not. If yes then they would like to do something about it.
