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?
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.
