In statistics, binary data is a statistical data type consisting of categorical data, that can take exactly two possible values, such as "A" and "B", or "heads" and "tails". It is also called dichotomous data, and an older term is quantal data. [1]

What is a binary variable? Definition and examples for multiple variable types and their uses. A binary variable is a variable with only two values.

For example, a binary variable (such as yes/no question) is a categorical variable having two categories (yes or no) and there is no intrinsic ordering to the categories.

What is a Binary Variable? A binary variable is a type of categorical variable that can take on only two possible values. These values typically represent two distinct categories or states, such as ‘yes’ or ‘no’, ‘true’ or ‘false’, and ‘0’ or ‘1’.

Mar 27, 2025 · Binary variables appear in various machine learning models, including: Decision Trees: Decision trees often use binary splits to partition the data into distinct groups. A binary split might involve checking whether a specific feature's value is above or below a threshold. These splits simplify decision-making processes and make the model ...

Binary variables are also known as boolean variables, dichotomous variables, flags, and indicator variables. Binary data is particularly useful in data analysis because despite being a special case of nominal, it also has all the properties of ordinal and interval data.

In statistics, binary variables serve crucial roles in hypothesis testing and regression analysis. For example: Logistic Regression: Used to model binary outcomes like pass/fail or yes/no scenarios.

Jul 29, 2017 · Possibly what is meant is that binary data consists only of 0's and 1's for "failures" and "successes" (notice that what you consider as a "success" is arbitrary) and follows a Bernoulli distribution.

In statistics, binary data is a statistical data type described by binary variables, which can take only two possible values. Binary data is used to represent the outcomes of Bernoulli trials, statistical experiments with only two possible outcomes.

Binary data refers to information that is represented in a binary format, which consists of two distinct states, typically represented as 0s and 1s. This type of data is fundamental in computing and digital communications, as it is the most basic form of data representation.
