Anscombe’s Quartet
Description
A dataset by Statistician Francis Anscombe that challenged the commonly held belief that “numerical calculations are exact, but graphs are rough” (Anscombe, 1973).
It comprises of 4 (the quartet!) small sub-datasets, each with 11 points that have different distributions but nearly identical descriptive statistics. It is perhaps the best argument for visualising data.
Format
A dataframe with 44 rows and 3 variables
