Which of the following is NOT a sampling tool for interviews?

The correct choice highlights that survey results from external databases are not considered a sampling tool for interviews. Instead, this option refers to collected data from sources that have already been analyzed or processed rather than a method for obtaining real-time, firsthand information through interviews.

Interview sampling tools, like random selection, pulling names from a hat, and using random generators, are techniques actively applied to choose participants from a larger population for conducting interviews. These tools ensure that the sample selected for interviews is representative and that the results are unbiased, reflecting a diverse range of responses from the entire population.

Using survey results from external databases does not involve the engagement of interviewees directly; rather, it relies on previously gathered information that may or may not relate to the specific context of the interviews being conducted. Thus, it stands apart as a different methodology, primarily focused on analysis of existing data rather than collecting new insights through interviews.
