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.
Data can be distributed (spread out) in different ways. But there are many cases where the data tends to be around a central value with no bias left or right, and it gets close to a Normal Distribution like this: A Normal Distribution. The Bell Curve is a Normal Distribution. And the yellow histogram shows some data that.
