The two variables of interest in this lab are: "percent change in mass" of bag and "sucrose molarity" in the bag solution. On a graph of these two variables, which would be the independent variable, and which would be the dependent variable?

Answer 1

An independent variable is the potential stimulus or cause, usually directly manipulated by the experimenter, so it could also be called a manipulative variable.

A dependent variable is the response or measure of results.
