## What is a dependent variable in an experiment?

A dependent variable is the variable being tested in a scientific experiment. The dependent variable is "dependent" on the independent variable. As the experimenter changes the independent variable, the change in the dependent variable is observed and recorded. When you take data in an experiment, the dependent variable is the one being measured.

## Can a variable be both independent and dependent at the same time?

• No. The value of a dependent variable depends on an independent variable, so a variable cannot be both independent and dependent at the same time. It must be either the cause or the effect, not both!

## What is the independent variable in this experiment paper towel?

• The independent variable in your experiment would be the brand of paper towel. The dependent variable would be the amount of liquid absorbed by the paper towel.

## What are the independent and dependent variables in a cause and effect?

## What is the independent and dependent variable in the moth experiment?What is the independent and dependent variable in the moth experiment?

The independent variable is the amount of light and the moth's reaction is the dependent variable. A change in the independent variable (amount of light) directly causes a change in the dependent variable (moth behavior). You are interested in learning which kind of chicken produces the largest eggs.

The variables in a study of a cause-and-effect relationship are called the independent and dependent variables. The independent variable is the cause. Its value is independent of other variables in your study. The dependent variable is the effect. Its value depends on changes in the independent variable.

## What are the two main variables in an experiment?What are the two main variables in an experiment?

In an experiment, there are two main variables: The independent variable: the variable that an experimenter changes or controls so that they can observe the effects on the dependent variable. The dependent variable: the variable being measured in an experiment that is “dependent” on the independent variable.
