Definition. Number is a grammatical category of nouns, pronouns, and verb agreement that expresses count distinctions (such as one or more than one). The count distinctions typically, but not always, correspond to the actual count of the referents of the marked noun or pronoun.
What is a 'Mean'. A mean is the simple mathematical average of a set of two or more numbers. The mean for a given set of numbers can be computed in more than one way, including the arithmetic mean method, which uses the sum of the numbers in the series, and the geometric mean method. However, all of the primary methods for computing a simple average of a normal number series produce the same approximate result most of the time.
