# Dependent variable

A dependent variable is a variable that is affected by the independent variable. In an experiment, the dependent variable is the variable being tested and the independent variable is the variable being manipulated.

##### What do you mean in dependent variable?

In mathematics, a dependent variable is a variable whose value is determined by another variable. In other words, the dependent variable is the variable being affected by the independent variable.

For example, in the equation y = mx + b, the dependent variable is y, while the independent variable is x. This is because the value of y is determined by the value of x (and the other variables, m and b).

##### What is difference between dependent and independent variable?

The difference between a dependent and independent variable is that a dependent variable is a variable that depends on another variable for its value, while an independent variable is a variable that does not depend on another variable for its value.

##### What is an example of a independent and dependent variable?

In mathematics, a dependent variable is a variable whose value depends on another value, called the independent variable. For example, the height of a person is a dependent variable because it depends on the person's age (the independent variable). How do you identify the dependent variable? The dependent variable is the variable that is being measured or observed. In an experiment, the dependent variable is the variable that is being affected by the independent variable.

### How do you remember independent and dependent variables?

There is a simple way to remember the difference between independent and dependent variables. An independent variable is one that stands alone and is not affected by the other variables in the experiment. A dependent variable is one that is affected by the independent variable.

In other words, the independent variable is the one that you are manipulating in the experiment, and the dependent variable is the one that is affected by the independent variable.
