An example of a double-barreled question would be the following: "do you think that students should have more classes about history and culture?" This question asks about two different issues: "do you think that students should have more classes about history" and "do you think that students should have more classes about culture?" Combining both questions into one makes it unclear what exactly is being measured, and as each question may elicit a different response if asked separately there is an increased likelihood of confusing the respondents. In other words, while some respondents would answer "yes" to both and some "no" to both, some would like to answer both "yes and no".
