s, respectively. If there are values in the data which extend beyond these endpoints, they are considered “outliers”, and plotted as points outside of the whiskers. In the example boxplot, you can see that there are three such outliers.</p>
A <strong>scatterplot</strong> is useful to see the relation between the values of two variables. For instance, it is likely that the total goals scored by each team will depend on the number of games they played. We can visually inspect this by plotting each team as
