What type of variable is yes or no?

The three types of categorical variables—binary, nominal, and ordinal—are explained further below. A simple version of a categorical variable is called a binary variable.

What type of variable is gender?

A categorical variable (sometimes called a nominal variable) is one that has two or more categories, but there is no intrinsic ordering to the categories. For example, gender is a categorical variable having two categories (male and female) and there is no intrinsic ordering to the categories.

What are examples of variables in research?

In an experimental example, if a study is investigating the differences between males and females, gender would be a variable (some subjects in the study would be men, and others would be women). If a study has only female subjects, gender would not be a variable, since there would be only women.

What are the four types of variables?

You can see that one way to look at variables is to divide them into four different categories ( nominal, ordinal, interval and ratio). These refer to the levels of measure associated with the variables.
