Normal Distribution

Explore NormalDistribution on MathWorld


The normal distribution is a probability distribution associated with many sets of real-world data. Due to the shape of this distribution, it is also famously called the "bell curve."

Normal distribution is a college-level concept that would be first encountered in a probability and statistics course. It is an Advanced Placement Statistics topic and is listed in the California State Standards for Probability and Statistics.

Prerequisites

Exponential Function: The exponential function is the function consisting of the base of the natural logarithm e taken to the power of a given variable.
Probability: Probability is the branch of mathematics that studies the possible outcomes of given events together with the outcomes' relative likelihoods and distributions.
Standard Deviation: The standard deviation is a statistic defined as the square root of the variance that measures how spread out a set of data is.
