Question

surveys quick check
a neighborhood organization wants to determine how many neighbors are interested in having a summer kick - off party. on tuesday evening, they call every fourth household in the neighborhood and ask if theyre interested in attending a summer kick - off party. what type of bias is exhibited in the situation? (7 point)

Explanation:

• Non - response bias occurs when some members of the population do not respond to the survey. In this case, it's Tuesday evening. Some households may be out (e.g., at work, running errands, having dinner outside), so they won't answer the call. This means the sample of respondents is not representative of the entire neighborhood population.
• Measurement - based bias is about errors in the measurement process (e.g., faulty questions, misinterpretation of questions). Here, the question is straightforward ("interested in attending a summer kick - off party"), so it's not measurement - based.
• Question - order bias is related to the order of questions affecting responses. There's only one question here, so this is not the case.
• Selection bias is about how the sample is selected. But in this situation, every household is called (assuming proper randomness in the calling process if it's a random sample of households). The main issue is non - response (not answering the call) rather than selection.

Answer:

Non - response bias.
