Based off of the hit television show NUMB3RS, this lesson has students create box-and-whisker plots for given data, and then determine which (if any) data points are outliers. Students determine outliers through two methods in this lesson: recognizing points that are significantly "far" from the quartiles on the box-and-whisker, and also by observing differences in the correlation of a scatterplot when possible outliers have been removed from the data set. Students practice both of these methods in this calculator-intensive lesson.
