dispersion
type: Concept
definition: Dispersion roughly refers to the degree of scatter or variability in a collection of observations. For example, individuals might differ about whether a political leader is doing a good job; children might respond differently to a method aimed at enhancing reading; and even in the physical sciences, measurements might differ from one occasion to the next because of the imprecision of the instruments used.
