The x-axis corresponds to the value of some variable, and the y-axis tells us something about how likely we are to observe that value. However, notice that the y-axis is labelled “Probability Density” and not “Probability”. WebLaplace used the normal distribution in the analysis of errors of experiments. The important method of least squares was introduced by Adrien Marie Legendre in 1805. Carl Friedrich Gauss who claimed to have used the method since 1794, justified it rigorously in 1809 by assuming a normal distribution of the errors. WebThe major properties of the normal curve are that it is symmetrical about the mean, unimodal, bell-shaped, points of inflection, the empirical rule, total area is 1 and area of each side is half, asymptotic, and it has a standard equation.
