An ordinary skewed curve, which is a departure (owing to disturbing factors) from the normal, is, like the normal curve, negatively accelerated in approaching the mode. The culprit, once again, is the extent to which the shape of the measurement distribution forms a normal bell curve or the human "nose" shaped "skewed normal" distribution.
