Question

In a study by Link and Mokdad (2005) comparing Web surveys with mail and telephone surveys about alcohol consumption, they found that:

a) Web surveys yielded the most accurate results
b) Mail surveys yielded the most accurate results
c) Telephone surveys yielded the most accurate results
d) Results varied based on the specific questions asked

Answer 1

In the study, Link and Mokdad found that survey results varied based on the specific questions asked, highlighting the importance of careful survey design and implementation. The accuracy of survey results can be influenced by selection bias, inaccurate responses, and technological challenges.

Step-by-step explanation:

In the study by Link and Mokdad (2005) comparing Web surveys with mail and telephone surveys about alcohol consumption, they found that d) Results varied based on the specific questions asked.

The accuracy of survey results can be influenced by various factors:

1. Selection bias: The shift away from landlines to cell phones can result in a sample that is not representative of the population being studied.
2. Inaccurate responses: People may lie, misremember, or provide socially desirable answers.
3. Technological challenges: Web surveys need to be compatible with different browsers and devices, and cannot detect multiple responses from the same person or misrepresentation of demographics.

Given these factors, it is important to carefully consider the design and implementation of surveys to ensure accuracy.
