This involves using different subjects in each condition of the experiment

a confounding variable is simply a variable that is known to have affected the experiment (either I.V or D.V). an extraneous variable becomes a confounding variable when it is known to have affected the result.
otherwise a good quiz, could do with more questions though i think.
