Challenge 29 - Comparing Distributions between Groups

Challenge 29 - Comparing Distributions between Groups
Challenge 29: Comparing Distributions between Groups Description: Imagine that you want to compare student test scores to find out whether there are anydifferences between the students' performances in 2020 (group 1) compared to 2019 (group 0). For example, you might want to find out whether there is an unusually high number of very good scorescompared to the other year, which could be a sign of cheating. Each student participated in the same three tests and received three test scores (Score 1, Score 2, andScore 3). How similar are the distributions of the three scores between the two groups? Which score distributiondiffers the most? The output should contain a visualization of the conditional distributions and a statisticaltest for the equality of mean and variance between the groups.
