Mia, Lily, and Scarlett are having a friendly competition to see who can identify outliers in a scatter plot the best. How can they spot these outliers?

• By focusing on data points that are hogging the spotlight in the center of the scatter plot.

• By observing data points that are playing 'hide and seek', significantly distant from the main cluster of points.
