The standard normal distribution is the normal distribution with a mean of zero and a standard deviation of one (the green curves in the plots to the right). It is often called the bell curve because the graph of its probability density resembles a bell.ome notable qualities of the normal distribution: 1  The density function is symmetric about its mean value. 2  The mean is also its mode and median. 3  68.268949% of the area under the curve is within one standard deviation of the mean.
A normal distribution is a distribution that is bell-shaped and symmetrical. The mean, median, and mode are all the same and coincide with the peak of the curve. The frequencies then gradually decrease at both ends of the curve. The normal distribution is also often called the bell-shaped curve because of its shape.hat is, it is the number or response category with the most observations for that variable. The midpoint of the normal distribution is also the point at which three measures fall: the mean, median, and mode.
