The dependent variable in this experiment is the coupons used in the store. The researchers were testing the effect of the coupon value on redemption, so they needed to measure whether or not the shoppers actually used the coupon. The brand selected is not the dependent variable because the researchers were not testing the effect of the brand on redemption. The supermarket and value of the coupon are independent variables that were manipulated by the researchers. Therefore, the best choice is B, coupons used in the store.
