Questions: What is an advantage of using interviews as a research method? They allow the researcher to maintain strict control of the data-collection process. They can affirm preconceptions and stereotypes. They reveal attitudes and beliefs inaccessible by any other means. They allow researchers to analyze data statistically and draw correlations.

The answer is: They reveal attitudes and beliefs inaccessible by any other means.

Explanation for each option:

1. They allow the researcher to maintain strict control of the data-collection process.
   This is incorrect. While interviews can be structured to some extent, they are generally more flexible and open-ended compared to other methods like surveys or experiments. This flexibility means that researchers have less control over the data-collection process, as the direction of the conversation can change based on the participant's responses.

2. They can affirm preconceptions and stereotypes.
   This is incorrect. While interviews can sometimes inadvertently affirm preconceptions if not conducted carefully, this is not an advantage. In fact, it is a potential bias that researchers need to be aware of and mitigate against.

3. They reveal attitudes and beliefs inaccessible by any other means.
   This is correct. One of the main advantages of interviews is their ability to uncover deep insights into participants' attitudes, beliefs, and experiences. The open-ended nature of interviews allows participants to express themselves in their own words, providing rich qualitative data that might not be captured through other methods.

4. They allow researchers to analyze data statistically and draw correlations.
   This is incorrect. Interviews typically produce qualitative data, which is not easily analyzed statistically. While qualitative data can be quantified to some extent, interviews are not primarily used for statistical analysis or to draw correlations. Instead, they are used to gain a deeper understanding of complex issues.
