2) an industrial designer wants to determine if the new design for a piece of office equipment will result in fewer errors. The designer sets up a machine with the old design in one room, and a machine with the new design in a second room. He counts how many errors are made using each of the two machines. In this study, the number of errors that are made would be
a a control variable
b the dependent variable
c the independent variable
d an extraneous variable
