In physics, Scattering is the study of collisions, especially of waves and particles (synonymous in quantum mechanics). In Elastic Scattering the objects are changed only in their motion, while in Inelastic Scattering the collision causes some change or produces a new object.
In statistics and statistical science, ''scatter'' is a synonym for Variance .
