Distributions

A statistical representation plotting all continuous (a.k.a. variable or numerical) values or data points of a dataset along a continuous scale. The plotting of these observations create a shape often referred to as a "bell curve" because of the appearance like a bell. The statistical measurement of the shape of the distribution is defined as normality, i.e., a normal distribution or non-normal distribution.
