Independent variable

An independent variable is a variable that is changed in a scientific experiment. Independent variables are the variables that the experimenter changes to test their dependent variable.

For example, a scientist is testing the effect of light and dark on the behavior of moths by turning a light on and off. The independent variable is the amount of light and the moth's reaction is the dependent variable. Also known as the manipulated variable.

Dependent Variable (Responding Variable)
A dependent variable is a 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.

For example, a scientist is testing the effect of light and dark on the behavior of moths by turning a light on and off. The independent variable is the amount of light and the moth's reaction is the dependent variable.

Final answer:

In scientific experiments, the independent variable is the variable that is changed or controlled by the experimenter, while the dependent variable is the variable that is being tested and is based on the changes made to the independent variable.

Step-by-step explanation:

In scientific experiments, the independent variable is the variable that is changed or controlled by the experimenter. It is also known as the manipulated variable. The dependent variable is the variable that is being tested and is based on the changes made to the independent variable. It is also known as the responding variable or outcome variable.
