Percent ranking answers what "% of values were less than Y." Kudos to @GrantSmith for the question.

This is useful for comparing test results in two populations. Imagine 67 respondents tested 75% or les whereas in group B 99 respondents scored 75% or less.


To calculate % rank, you calculate the rank and divide each rank by the count of values.

    Thank you for the video. I have a question on using View. When I did the group by User and Exam to get the Sum of Score, the original column `Score` would not be in the dataset after the Group By. Then how did you use SUM(`Score' ) in the BeastMode to calculate the percentile rank?

    Thank you
