Graphical presentation of cephalometric norms for Saudi children. A graph (Wiggle) in which cephalometric norms for Saudi children (mean age: 12.2 years) are plotted on a central vertical line. The readings of plus or minus one standard deviation of each norm are plotted on either side of the central line in a way that all the Class II readings were placed on the left side and the Class III readings were placed on the right side of the central line.
