Binary measure is a statistical term that refers to a type of measurement or variable that can only take on two distinct values or categories. It is characterized by a dichotomous nature, meaning it provides a "yes" or "no," "true" or "false," or some other pair of mutually exclusive choices. The values of a binary measure are typically coded as 0 and 1, or as any other set of distinct symbols, representing the absence or presence of a particular characteristic or phenomenon.
Binary measures are commonly used in various fields, including psychology, sociology, economics, and information technology. In psychology and sociology, binary measures can represent traits such as gender (male or female) or binary categories like married or unmarried. In economics, binary measures can signify choices like "purchased" or "not purchased" or "employed" and "unemployed."
In the field of information technology, binary measures usually refer to binary variables that are represented by bits (binary digits), which are the fundamental units of information in computing systems. These binary measures can be used to indicate the status of a switch (on or off), the presence or absence of a file, or any other digital state.
Binary measures are significant in data analysis as they allow for straightforward statistical analyses, such as calculating proportions, frequencies, and conducting statistical tests like the chi-square test, logistic regression, or other specialized techniques designed for categorical variables.
The word "binary" originates from the Latin word "binarius", meaning "consisting of two" or "double". It is derived from the Latin word "bini", which means "two by two".
