Question

You are reading a blog post about the relationship between Arameans and Calipari. You are not an expert on these two variables or the domain where this data comes from. Relying on your statistical expertise, use the below plot to investigate these two variables. Compare notions of spread and skew for the Arameans and Calipari variables. Sketch density curves for each variable. Do not worry about the exactness of the y-axis. Concern yourself with the general shape of the density curves. Bart Bivariate claims that there is an outlier in the dataset, while Uri Univariate says that neither variable has any outliers. Explain how they are both right. You may use images in your explanation. Given this above plot, what claims can you make about the relationship between these two variables?

Explanation / Answer

(a) Bothe the variables seem to be bimodal and peak around two values.

(b) Given on the opposite end of the scatterplot.

(c) The point in two-red circles is an outlier by Bart Bivariate claim while those in single circles are by Uri Univariate.
