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.
a distribution which is normal when the log values of the variable are considered. normal distribution. a graph of the distribution appears as a bell-shaped curve which is symmetrical on the two sides of the vertical axis through the peak of the curve. Called also gaussian distribution.parent distribution. the distribution (population) that was originally sampled. distribution which is normal when the log values of the variable are considered. normal distribution. a graph of the distribution appears as a bell-shaped curve which is symmetrical on the two sides of the vertical axis through the peak of the curve.
