Figure 2.

Box plots for three lesion features from the dataset: size (maximum linear size), shape (irregularity), and enhancement texture (maximum correlation coefficient). The width of the notches in a given box is proportional to the interquartile range of the data and provides a visual indication of possible difference in groups. The horizontal lines within the boxes indicate the median of the set, whereas the edges of the boxes indicate the 25th and the 75th percentiles. The crosses indicate outliers.
