Binary variable

Explanation:

These are variables that can only take 2 values.

When a variable has only two possible levels, it is referred to as binary or dichotomous. Most of the time, these variables can be asked in a “yes/no” manner. A binary variable is something like a person's smoking status.

Numerical and categorical. Then, each category is divided into two subcategories: discrete or continuous for numeric variables, and nominal or ordinal for categorical variables.

In their investigations, psychologists frequently use several dependent variables. The main justification for this is that it makes it simple for them to quickly and cheaply respond to more study inquiries.

A naming scale is one in which variables are merely “named” or labelled, without regard to their order. Beyond just identifying them, the variables on an ordinal scale have a precise order.

Therefore, Labels, an order, and a specified interval are provided for each of the variable possibilities in an interval scale.
