1857, “mathematical condition of being at right angles,” from normal + -cy. Associated since c.1920 with U.S. president Warren G. Harding and derided as an example of his incompetent speaking style. Previously used mostly in the mathematical sense. The word prefered by purists for “a normal situation” is normality (1849).
A word used by President Warren Harding to describe the calm political and social order to which he wished to return the United States after the idealism and commotion of the presidency of Woodrow Wilson.
Note: Normalcy has been used as a general term for the political climate in the United States in the early 1920s.
noun, Statistics. 1. a theoretical frequency distribution represented by a normal curve. noun 1. (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 (nôr’məl) […]
- Normal distribution curve
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 […]
noun, Mathematics. 1. a normal subgroup.
noun, Statistics. 1. a value x such that the integral of a normal curve over all those values of the independent variable less than x is equal to the given probability.
