Textbook Question
Chapter 1.4, Problem 20E
Order of choices: When multiple-choice questions are asked, the order of the choices is usually changed each time the question is asked. For example, in the 2016 presidential election, a pollster would ask one person “Who do you prefer for president, Hillary Clinton or Donald Trump?” For the next person, the order of the names would be reversed: “Donald Trump or Hillary Clinton?” If the choices were given in the same order each time, do you think that might introduce bias? Explain.
