The independent variable that was manipulated in the experiment was the face value of the coupon, with one group being offered 15-cent coupons and the other group being offered 50-cent coupons. This variable was deliberately changed by the researchers in order to test its effect on the likelihood of coupon redemption. Brand usage, likelihood of cashing the coupon, and individual shoppers were not manipulated in this experiment, and were instead likely measured as dependent variables or controlled for as extraneous variables.
