The normal or Gaussian probability distribution is actually a family of distributions of the same general form, differing only in their location and scale parameters, commonly called the mean and standard deviation.

The shape of a graph of the distribution consists of a central bulge centered on the mean with about 99% of the area under the density curve between the mean plus and minus three standard deviations. Its resemblance to the shape of a bell has led to the shape of the normal distribution being called the 'bell curve'.
