Normal Distribution

A normal distribution is an arrangement of a data set in which most values cluster in the middle of the range and the rest taper off symmetrically toward either extreme.

 

Normal Distribution Example:

Most people are average height, while the number of people taller and shorter than the average are roughly equal. Furthermore, the number of extremely tall or extremely short people is relatively small.

 

Aka: The Bell Curve
