Question

Which of the following best describes a limitation of interviews and questionnaires?

a. They may suffer from social desirability bias.
b. They provide in-depth insights into complex topics.
c. They guarantee a high response rate.
d. They are always cost-effective.

Answer 1

The main limitation of interviews and questionnaires is social desirability bias, which leads to inaccurate data. They also do not guarantee a high response rate and are not always cost-effective. So, the correct answer is option a.

Step-by-step explanation:

The main limitation of interviews and questionnaires is that they may suffer from social desirability bias, which occurs when people respond in a way that they think is socially acceptable rather than providing truthful answers. This can lead to inaccurate data.

Another limitation is that surveys and interviews do not guarantee a high response rate (limiting response rate), which can result in a biased sample. Lastly, interviews and questionnaires are not always cost-effective (not always cost-effective), as they require resources such as time, personnel, and sometimes incentives to encourage participation. So, the correct answer is option a.
