noun, Statistics.
a theoretical frequency distribution represented by a normal curve.
(statistics) a continuous distribution of a random variable with its mean, median, and mode equal, the probability density function of which is given by (exp-[(x–μ)²/2σ²]/σ√(2π)) where μ is the mean and σ² the variance Also called Gaussian distribution
normal distribution
A theoretical frequency distribution for a set of variable data, usually represented by a bell-shaped curve symmetrical about the mean.

    In statistics, the theoretical curve that shows how often an experiment will produce a particular result. The curve is symmetrical and bell shaped, showing that trials will usually give a result near the average, but will occasionally deviate by large amounts. The width of the “bell” indicates how much confidence one can have in the […]
