Figure 5. Drill-Torque notched box plot: depicts the interquartile range (IQR) between the 25th and 75th percentile of the specific biomaterial tested where 50% of the data points were located.

Additionally, the upper whiskers represent data within the 75th percentile +1.5 times the IQR. The lower whisker delimits data of the 25th percentile – 1.5 times the IQR. Circles [Inline graphic] represent the outliers. Within the boxes the notches mark the confidence interval based on the median +/− 1.58 (IQR/sqrt of n) [n = number of measurements]. Additionally, the mean value is indicated by a black square [Inline graphic] and the cross symbol [+] displays the standard deviation.
