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 Gaussian distribution can be depicted as a bell curve -- or a normal curve -- using a scatter chart with smooth lines and markers. In Microsoft Excel you can use the NORMDIST formula to calculate the randomness of your data set using the mean and standard deviation.
