The y-axis shows the number of hits needed to crack open either a dry or a fresh nut with a standardized nut cracking device. The boxplot shows the upper and lower quartile with the median presented by the thicker horizontal line. The whiskers present the maximum and minimum range of the data (excluding outliers). The circles show individual outliers.
