Answer 2

There are two types of variables-independent and dependent. ... Answer: An independent variable is exactly what it sounds like. It is a variable that stands alone and isn't changed by the other variables you are trying to measure. For example, someone's age might be an independent variable.

Answer 3

if you can vary it at will, then it's "independent"
if something changes as a result, then it's "dependent".
