Interval widths between adjacent speech segments on the Lewis-Sherman scale of stuttering severity were estimated by means of a scaling procedure. Analyses of the data indicated that the lower three intervals were less than half as wide as the others. This would suggest that the scale possesses ordinal rather than interval properties. Several implications are discussed.
