Problem 30 - BIG IDEAS MATH Algebra 2: Common Core Student Edition 2015

Question

In Exercises 29–32, determine whether the survey question may be biased or otherwise introduce bias into the survey. Explain your reasoning. "Do you think that renovating the old town hall would be a mistake?"

Step-by-Step Solution

Answer

Yes, the survey question 'Do you think that renovating the old town hall would be a mistake?' may introduce bias due to its suggestive phrasing which can lead the respondents towards a negative response.

Step 1: Identify the Research Topic

The research topic is 'renovation of the old town hall'. The survey question is about obtaining public opinion on whether renovating the old town hall should be undertaken or not.

Step 2: Analyze the Survey Question

The phrasing of the question 'Do you think that renovating the old town hall would be a mistake?' is suggestive, creating a presumption that the renovation could be a wrong decision. Thus, the question might introduce bias by leading respondents towards a negative response.

Step 3: Evaluate Potential Bias

Bias in a survey question can come from loaded language, leading questions, or when the question assumes something to be true which may not necessarily be. In this case, the wording of the question '...would be a mistake?' can imply that a negative outcome is expected, leading to the introduction of bias because it might unduly influence the respondent towards a negative opinion. An unbiased phrasing could be: 'What is your opinion on the renovation of the old town hall?'

Key Concepts

Research Topic Identification

Effective research begins with clearly identifying the research topic, which acts as a compass guiding all subsequent processes, including the construction of survey questions. When identifying a research topic, it's crucial to narrow down the subject matter to a precise inquiry that seeks to unravel specific insights.
In the context of the given exercise, the topic at hand is the 'renovation of the old town hall'. It is a clear and focused area that demands public opinion, setting the foundation for targeted questions.

• Ensuring that the topic is specific avoids ambiguity and helps in crafting direct questions.
• It must hold relevance to the respondents to elicit meaningful and engaged answers.
• Finally, the topic should be void of any preconceived notions or biases to maintain the integrity of the research.

When the research topic is well-defined and free of bias, it serves to enrich the data and analysis that will follow.

Bias Evaluation in Surveys

Bias evaluation is a critical step in survey design, protecting the validity of the gathered data.

• Bias can stem from the way questions are worded, the sequence in which they are asked, the response options provided, or pre-existing societal attitudes.
• It is also important to consider the potential for self-selection bias, where individuals with strong opinions are more likely to participate, skewing the results.
• Cultural and language differences can also influence the responses, adding another layer of potential bias.

In the given exercise, evaluating the potential bias involves a careful examination of the language used in the survey question. The phrase 'would be a mistake' assumes a negative predisposition towards the renovation and could influence respondents to agree with that sentiment, leading to biased outcomes. To ensure data integrity, researchers must scrutinize survey questions, removing any leading or loaded language that may distort the results.

Phrasing Survey Questions

The phrasing of a survey question is a determining factor in soliciting accurate and unbiased information.
There are several key points to consider:

• Questions should be neutral and straightforward, avoiding any language that could lead or prompt the respondent towards a particular answer.
• Complex or double-barreled questions, which address more than one issue at a time, should be avoided since they can confuse respondents and yield unreliable data.
• To avoid misinterpretation, the terminology used must be clear and relatable for the target demographic of the survey.

Looking at our exercise, rephrasing the question to 'What is your opinion on the renovation of the old town hall?', as suggested in Step 3, mitigates bias. This alternative is open-ended and non-presumptive, thus inviting a range of honest and thoughtful responses; it does not sway the respondent in any predetermined direction. The redesign of this question demonstrates the importance of careful consideration in question wording to uphold the integrity of survey research.
