Scatterplots for outlier detection

A scatterplot is another handy method to identify outliers visually. Although it is usually used to plot two variables against each other to inspect their relationship, using the trick from the video, you can plot a scatterplot with only one variable to make the outliers stand out.

matplotlib.pyplot is loaded as plt. The data is available as prices.
