5 years ago - Add a visualization of p-value and grades distribution in the report
- Outliers treatment: What does it mean for a student to have a final math grade of 0% ? Did they drop out ? How much do these observations affect the mean grades ? Test the outliers effect on the results by removing them from the data set
- Be more careful when interpreting the p-value : Mention in the report that the large number of observations might have impacted the significance.
