    There's a Maths forum but I ain't bothered myself, you couldhave just searched Google for "characters of a normal distribution curve" and clicked on the first link:

    Some of the important characteristics of the normal curve are:

    1. The normal curve is a symmetrical distribution of scores with an equal number of scores above and below the midpoint of the abscissa (horizontal axis of the curve).
    2. Since the distribution of scores is symmetrical the mean, median, and mode are all at the same point on the abscissa. In other words, the mean = the median = the mode.
    3. If we divide the distribution up into standard deviation units, a known proportion of scores lies within each portion of the curve.
    4. Tables exist so that we can find the proportion of scores above and below any part of the curve, expressed in standard deviation units. Scores expressed in standard deviation units, as we will see shortly, are referred to as Z-scores.
