These deductions become hypotheses that are tested experimentally. The experimental results are then used to confirm the postulates or change them if necessary. c. ?Data from experiments are used to produce theories of learning. Once the theory is formed, there is no need to test the theory, since theory is more important than data. d. ?Any of the choices might be correct, depending on the circumstances. e. ?None of the choices are correct.
