a graph of a NORMAL DISTRIBUTION of virtually any trait within a population

a graph of a solution to a linear problem (ie

a plot of normal distribution of a given data set

a bell-shaped curve that represents theoretical frequency distribution.

A frequency distribution statistics. Normal distribution is shaped like a bell.

The normal or bell-shaped curve that is assumed to underlie human abilities. It is frequently invoked to justify allocating grades along a similar curve, but this is ill-advised: university students are not randomly selected, and even if they were, it is hoped that effective teaching would destroy any normal distribution of outcomes.

a.k.a. the normal curve, is an idealized statistical graph of a frequency (or relative frequency) distribution for a random variable quantity whose mean, median and mode are identical; the distribution is symmetrical about this (center-line) value.

(noun) A normal curve; normal distribution, a theoretical distribution with finite mean end variants.

A distribution of values that is symmetrically largest around the average.
