A plot representing corresponding observed values of two variables ''x'' and ''y'' as points in Cartesian coordinates. If the two variables are functionally related, the points will be bunched, but if they are not functionally related, the points will be scattered uniformly over the plane. Scatter diagrams are used to explore the influence of one variable upon another, strong relationships being revealed as a concentration around a definite curve.

The average time until the next occurrence of a defined event. When the time to the next occurrence has a geometric distribution, the return period is equal to the inverse of probability of the event occurring in the next time period, that is, ''T'' = 1/''P'', where ''T'' is the return period, in number of time intervals, and ''P'' is the probability of the next event's occurrence in a given time interval.

An approximate law of scattering of electromagnetic waves by molecules and particles small compared with the wavelength of the illumination at wavelengths for which absorption is sufficiently small. According to this law, first derived in 1871 by Lord Rayleigh using simple dimensional arguments, scattering in all directions by an object is inversely proportional to the fourth power of the wavelength of the illumination. Scattering of sunlight by air molecules does not obey this law exactly, although it is a good approximation. Rayleigh's scattering law also predicts that scattering by a particle is proportional to the square of its volume. Compare Mie theory.
