Consider the fisher-price chatter telephone photo above. toy designers at fisher-price conduct marketing research to discover how children play and what they like to play with. for fisher-price, the immediate research objective is to decide whether to continue to market the old chatter telephone design or a new design. the old, original chatter telephone was simply a wooden phone with a dial that rang a bell. however, observers noted that the children kept grabbing the receiver like a handle to pull the phone along behind them. so a designer created a new chatter telephone, one with wheels, a noisemaker, and eyes that bobbed up and down. what would be the most likely measure of success fisher-price would use to determine which design should be selected?
