The dependent variable is the variable being tested and measured in an experiment, and is ‘dependent’ on the independent variable. In an experiment, the researcher is looking for the possible effect on the dependent variable that might be caused by changing the independent variable.
What is a variable in coding?
In computer programming, a variable or scalar is a storage location (identified by a memory address) paired with an associated symbolic name, which contains some known or unknown quantity of information referred to as a value. The latter is abstract, having no reference to a physical object such as storage location.

Four Types of Variables You can see there are four different types of measurement scales (nominal, ordinal, interval and ratio). Each of the four scales, respectively, typically provides more information about the variables being measured than those preceding it.
Why do we use variables?
Variables are used to store information to be referenced and manipulated in a computer program. They also provide a way of labeling data with a descriptive name, so our programs can be understood more clearly by the reader and ourselves. It is helpful to think of variables as containers that hold information.
