QUESTION:•There are three types of variable, list and define them.
ANSWER:
• Independent variable tells us what we are testing, stands on its own, usually comes after IF•Dependent variable tells us what/how we are measuring, depends on the independent variable, usually comes after THEN•Control variable stays the same and allows the experiment to be done numerous times with the same result because it causes the experiment to only test the independent and dependent variables.
