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.
The normal curve is a hypothetical distribution of scores that is widely used in psychological testing. The normal. curve is a symmetrical distribution of scores with an equal number of scores above and below the midpoint. Given. that the distribution of scores is symmetrical (i.e., an equal number of scores actually are above and below the. midpoint) the mean, median, and mode all fall at the same point.
