Independent, Dependent and controlled variables

Things that are kept the same to ensure experiment results are due to the independent variable and not external factors are called:

• Control Variables

• Control Groups

• Independent Variables

• Dependent Variables

The variable the is changed on purpose to see its effects on something is called:

• Interdependent Variable

• Controlled Variables

• Independent Variable

• Dependent Variable

The variable that is being tested, counted, or measured is known as

• Controlled Variable

• None of these

• Independent Variable

• Dependent Variable

An investigation found that more potatoes would be produced on a farm if the soil was fertilised more.

What is a controlled variable or constant in this experiment?

• Number of potatoes

• Type of ball

• Same drop height

• Height of bounce

• Same surface
