It should be evident from Figures that the following are true: (a) The frequency distribution from Table III yields a perfectly straight line when as a percentage is plotted against A on a normal-arithmetic graph paper. (6) The frequency distribution of the ACE scores apparently is quite near to normal because the points of their graph on.
