I've a small dataset with just 2 columns that you can download here. The first column represents the amount of money earned every 1000 pageviews, and the second is the number of pageviews. I'd like to check if there is a relation between the two variables but, since the scatter plot looks quite uncorrelated, I'd like to separate the data in clusters and also delete the outliers.
I'm trying to play with the data. Can you give me some suggestion on where to start from?
