Is binary variable continuous?

Binary variables are those that take on exactly two values, such as 0 and 1 or True and False or Male and Female. For analysis purposes, they can be considered either continuous or categorical. In general it doesn't matter which way you think about them.

Is binary continuous or categorical?

Binary variables are nominal categorical variables that contain only two, mutually exclusive categories.

What is the difference between a categorical and continuous variable?

Categorical variables, aka discrete variables. These come in only a fixed number of values – like dead/alive, obese/overweight/normal/underweight, Apgar score. Continuous variables. These can have any value between a theoretical minimum and maximum, like birth weight, BMI, temperature, neutrophil count.

What is an example of a binary variable?

A binary variable is a variable that has two possible outcomes. For example, sex (male/female) or having a tattoo (yes/no) are both examples of a binary categorical variable. A random variable can be transformed into a binary variable by defining a “success” and a “failure”.
