French Equivalent: Classe

Apart from its usage in the customary colloquial sense this word has some mild specialisation in the theory of frequency distributions. The total number of observations made upon a particular variate may be grouped into classes according to convenient divisions of the variate range in order to make subsequent analysis less laborious or for other reasons. A group so determined is called a class.

The variate values which determine the upper and lower limits of a class are called class boundaries; the interval between them is the class interval; and the frequency falling into the class is the class frequency.
