What are the criteria?
300
The variable that is being measured.
What is the dependent variable?
300
What is a dependent variable?
The dependent variable is the variable that responds to the independent variable.

Mr. S thinks that the "Quantum" Duracell battery has more energy than the regular Duracell battery. He wants to test out his hypothesis by doing the following experiment. He will use one new "Quantum" battery to power a flashlight and a old regular battery to power a clock. He leaves the flashlight and clock on until it turns itself off. He will record the time. Is this experiment considered a controlled experiment?
It is not a controlled experiment because there is more than one independent variable.
500
The group in an experiment is unchanged and used for comparison
What is the control group?
500
The changes made to make a model better.
What are the modifications?
500
Name the dependent variable.

What makes an experiment considered a controlled trial?
A trial with no independent variable.
