Box plot



"A boxplot, or box and whisker diagram, provides a simple graphical summary of a set of
data. It shows a measure of central location (the median), the average, and measures of dispersion. Boxplots are especially useful when comparing two or more sets of data."(Notes)
So in this data set, it shows the median score of each machine as well as each percentile. http://itl.nist.gov/div898/handbook/eda/section3/boxplot.htm
