Which term describes a variable with only two possible values, such as 0 and 1?

Two-valued variables are described as binary. This means the variable can take only two possible values, such as 0 and 1, or yes and no, true and false. Binary is a specific label for a dichotomous type of data. It sits within categorical data, but unlike broader categorical cases that may have many categories, a binary variable has exactly two. This distinction matters in analysis because binary (0/1) coding is commonly used in models like logistic regression, where outcomes are interpreted as the effect of moving from one category to the other.
