Relative frequency  (RELATIVE frequency)

The arrangement of members of a population in various categories or classes of specified attribute or variable produces a frequency distribution1, often called a distribution1 for short. The ratio of the number in the individual groups or cells—the cell frequency2 or class frequency2— to the total number is called the relative frequency3 (cf. 133-5) in that group. The term absolute frequency2 is synonymous with class frequency. In demography the term structure4 is often used instead of frequency, and the structure of a population is often studied with respect to a given attribute such as age.
