Questions: The way that a question in a survey is worded often has an effect on the responses.

The answer is: often has.

Explanation:

1. Wording Effects in Surveys: The way a question is worded in a survey can significantly influence the responses. This is known as the "wording effect." The choice of words, phrasing, and even the order of questions can lead to different interpretations and responses from participants.

2. Examples of Wording Effects:

   • Leading Questions: Questions that suggest a particular answer can bias responses. For example, asking "How much do you agree with the excellent job the government is doing?" presupposes that the government is doing an excellent job, which may lead respondents to agree more readily.
   • Complex or Ambiguous Language: Using complex or ambiguous language can confuse respondents, leading to inaccurate or varied responses. Clear and simple language helps in obtaining more reliable data.
   • Framing Effects: The way information is presented can affect decision-making and responses. For instance, asking about "tax relief" versus "tax cuts" can evoke different emotional responses and opinions.

3. Research and Theories: Numerous studies in psychology and social sciences have demonstrated the impact of question wording on survey results. For example, the framing effect is a well-documented phenomenon in behavioral economics and psychology, showing how different presentations of the same information can lead to different decisions.

In conclusion, the wording of survey questions often has a significant effect on the responses, making it crucial for researchers to carefully design their questions to minimize bias and obtain accurate data.
