Document Summary

Often, a researcher wants to know how an iv affects several different dvs. One way = measure them in the same order for all ps. Another way = to counterbalance the order in which dvs are measured. When the iv is a construct that can only be manipulated indirectly (ex: emotions) then an additional measure of that iv is included as a manipulation check: done to confirm the iv was successfully manipulated. Usually done at the end of the procedure to ensure that the effect of the manipulation lasted throughout the entire procedure. When measuring multiple dvs, it is important to operationally define and measure the same contruct in different ways. Ex: the dv stress" can be defined in many ways. Including multiple ivs allows researchers to answer questions about whether the ffect of one iv depends on the level of another: an interaction etween the ivs. The most common approach to including multiple ivs in an experiment.
