A dependent variable is what you measure in the experiment and what is affected during the experiment. The dependent variable responds to the independent variable. It is called dependent because it “depends” on the independent variable.

What are examples of independent and dependent variables?

How do you explain independent and dependent variables?

The independent variable is the one the experimenter controls. The dependent variable is the variable that changes in response to the independent variable. The two variables may be related by cause and effect. If the independent variable changes, then the dependent variable is affected.

Is income a dependent variable?

A factor or phenomenon that causes or influences another associated factor or phenomenon called a dependent variable. For example, income is an independent variable because it causes and influences another variable consumption.

Is time an independent variable?

What is a dependent variable in research?

Definitions. Dependent Variable. The variable that depends on other factors that are measured. These variables are expected to change as a result of an experimental manipulation of the independent variable or variables. It is the presumed effect.

What is the dependent and independent variable in a survey?

The independent variables affect the dependent variables. In the survey, researchers can view the respondents as dependent variables and the questions as independent variables. The researchers can choose what the questions will be, giving them control over them.

What is the difference between dependent and independent variable?

An independent variable is the cause. Its value is independent of other variables in your study. A dependent variable is the effect. Its value depends on changes in the independent variable.

How do you know what the dependent variable is?

An easy way to think of independent and dependent variables is, when you’re conducting an experiment, the independent variable is what you change, and the dependent variable is what changes because of that. You can also think of the independent variable as the cause and the dependent variable as the effect.

What is the definition of dependent variable in science?

The dependent variable is the variable being tested and measured in an experiment, and is ‘dependent’ on the independent variable. An example of a dependent variable is depression symptoms, which depends on the independent variable (type of therapy).

How do you define an independent variable?

Answer: An independent variable is exactly what it sounds like. It is a variable that stands alone and isn’t changed by the other variables you are trying to measure. For example, someone’s age might be an independent variable.
