Question

a fashion store is interested in attracting new customers using different marketing strategies. they prepare ads for dresses announcing four different levels of discounts: 10%, 20%, 30%, or 40%. they prepare two sets of ads: one in black and white, the other in color. one hundred females are asked to rate the attractiveness of the sale on a scale of 1 to 10. the response variable is/are
○ the different levels of discounts.
○ the two sets of ads.
○ the marketing strategies.
● the attractiveness of the sale.

Explanation:

In a statistical or experimental context, the response variable (also called the dependent variable) is the outcome being measured or observed. Here, the fashion store is measuring how attractive the sale is (rated on a 1 - 10 scale) in response to different marketing strategies (discount levels, ad color). The other options (discount levels, ad sets, marketing strategies) are independent variables or factors being manipulated, not the response. So the response variable is the attractiveness of the sale.

Answer:

the attractiveness of the sale.
