We say the data is normally distributed: The Normal Distribution has: 1  mean = median = mode. 2  symmetry about the center. 3  50% of values less than the mean. 4  and 50% greater than the mean.
The probability density function of the normal distribution with mean and variance (equivalently, standard deviation) is an example of a Gaussian function, (See also exponential function and pi. ). If a random variable has this distribution, we write ~ .If and, the distribution is called the standard normal distribution and the probability density function reduces to. The image to the right gives the graph of the probability density function of the normal distribution various parameter values.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.
