The only way to test a particular variable for sure is to leave all other variables constant, and if a change in ONE variable creates an overall change, then you know that that variable caused it. But if you change 2 variables, and something changes, you don't know which one changed it for sure. So, one variable at a time. A full experiment can test many variables, though. better just to test one variable at a time that way one knows that any changes observed are accounted for by that variable.
Define the Variables. There should be three categories of variables in every experiment: dependent, independent, and controlled. Dependent -- is what will be measured; it's what the investigator thinks will be affected during the experiment.For example, the investigator may want to study coffee bean growth.here should be three categories of variables in every experiment: dependent, independent, and controlled.
