Chapter 1, Problem 1.3.34
Determine whether the survey question is biased. If the question is biased, suggest a better wording.
How does the media influence the opinions of voters?
Verified step by step guidance1
Step 1: Understand the concept of bias in survey questions. A biased question is one that leads respondents toward a particular answer or assumes something that may not be universally true. It can influence the results and reduce the reliability of the survey.
Step 2: Analyze the given question: 'How does the media influence the opinions of voters?' This question assumes that the media does influence voters' opinions, which may not be true for all respondents. This assumption introduces bias into the question.
Step 3: Identify the issue with the wording. The phrase 'How does the media influence' presupposes that there is an influence, which could lead respondents to answer in a way that aligns with this assumption rather than providing their unbiased opinion.
Step 4: Suggest a better wording for the question. A more neutral phrasing could be: 'What role, if any, does the media play in shaping the opinions of voters?' This removes the assumption of influence and allows respondents to provide a broader range of answers.
Step 5: Ensure that the revised question is clear, neutral, and open-ended. This helps in collecting unbiased data and ensures the survey results are more reliable and representative of the respondents' true opinions.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Survey Bias
Survey bias occurs when the wording of a question leads respondents to a particular answer, thus skewing the results. This can happen through leading questions, loaded language, or a lack of neutrality. Identifying bias is crucial for ensuring that survey results accurately reflect the opinions of the population being studied.

Media Influence
Media influence refers to the ways in which media outlets shape public perception and opinion, particularly during elections. This can include framing issues, highlighting certain viewpoints, or providing selective information. Understanding this concept is essential for analyzing how voters' opinions may be swayed by media coverage.
Question Wording
The wording of survey questions is critical in determining how respondents interpret and answer them. Neutral and clear wording helps to minimize bias and ensures that the responses are genuine reflections of the respondents' views. Crafting well-structured questions is vital for obtaining reliable data in surveys.

Textbook Question
Volunteers for an experiment are numbered from 1 to 90. The volunteers are to be randomly assigned to two different treatment groups. Use a random number generator different from the one you used in Exercise 21 to choose 45 subjects for the treatment group. The other 45 subjects will go into the control group. List the subjects, according to number, in each group. Tell which method you used to generate the random numbers.
