Statistics refers first to a branch of mathematics that specializes in enumeration data and their relation to measured data. It may also refer to a fact of classification, which is the chief source of all statistics. In the singular, a statistic refers to a derived numerical value, such as a mean, a coeffecient of correlation, or some other single descriptive concept. It may also refer to an idea of an average, such as a median, or standard deviation, or a value computed from a set of data. [1]
