Normal Distribution

Normal Distribution is a statistical term frequently used in psychology and other social sciences to describe how traits are distributed through a population. Often referred to as “bell curves” (because the shape looks like a bell) it tracks rare occurrences of a trait on both the high and low ends of the “curve” with the majority of occurrences appearing in the middle section of the curve. The most commonly known example comes from IQ tests with the majority of the population scoring within the “normal” or middle-range of intelligence.
