When a question is biased, one answer in a survey question seems better than the other.
See solution.
Practice makes perfect
We want to explain why the given survey question may be biased.
Survey
Do you agree that our school cafeteria should switch to a healthier menu?
To do so, let's take a closer look at some parts of the question. Let's start with the beginning.
Do you agree [...]
The verb agree suggests that the asking person is for the idea, so it will be harder for a respondent to answer no. It would be better to use words that do not show the personal preference of the survey makers, because such a question can encourage a particular response. To avoid that, we could replace agree with think.
Do you think [...]
Let's move to the end of the question.
[...] healthier menu ?
First, this can make respondents think that the current menu is not healthy. However, we do not tell specifically what would change in the menu that will make it healthier. Therefore, we should provide more information about the change to let respondents give more accurate opinions. Let's replace healthier with some specific information.
[...] healthier menu ? ⇕ [...] menu with more vegetables and fruit in it?
Finally, we can rewrite the whole question that is now unbiased.
