A Box Plot is a graph used to show the distribution of a single field (variable) of data. All data values are shown. The middle line represents the median; the left and right sides of the box show the medians of the lower and upper halves of the data. The ends of the line segments attached to the box extend to the smallest data value and the largest data value. Thus, a box plot shows the distribution of all data values from least to greatest, separated into quarters. |
