Box Plot




Box Plots display a set of numerical data based on their five-number summaries: the smallest observation( sample minimum), lower quartile (Q1), median quartile (Q2), upper quartile (Q3), and largest observation (sample maximum). They also display data that would be considered an outlier. The box plot above is showing information gathered about the water quality of Volunteer Creek. This is a good way to determine the most common results, compared to abnormally high or low results.
