Question

The essential objective of the drop-off survey is:

A) low cost because there is no mail-out expense
B) to gain a prospective respondent's cooperation
C) to minimize item omission bias
D) to combine computerization with telephone surveying
E) all of the above

Answer 1

The main objective of the drop-off survey is to minimize item omission bias, by encouraging complete responses and enhancing data accuracy. It is cost-effective and seeks respondent cooperation, but does not combine computerization with telephone surveying.

Step-by-step explanation:

The essential objective of the drop-off survey is to minimize item omission bias. Item omission bias occurs when respondents skip questions, which can result in incomplete or skewed data. Drop-off surveys, as opposed to mail-out or telephone surveys, are designed to be completed at the respondent's convenience, which can increase response rates and reduce the number of omitted items. They are typically cheaper than mail-out surveys because there are no postage expenses, and they can secure the cooperation of potential respondents effectively. However, this does not necessarily involve combining computerization with telephone surveying.

One of the potential problems with samples that could explain why all 11 participants responded 'NO!' to a previous survey is a biased sample, where the group of respondents does not accurately represent the target population. Reference [73] highlights that mail surveys can suffer from low response rates and potentially unverified respondents, which can affect the reliability of the survey data. Additionally, technological challenges in modern surveys, as mentioned in [40], add complexity to obtaining accurate response rates and achieving representative samples when using web-based methods
