Which of the following is NOT a type of data collection method?

Quantitative analysis encompasses a range of statistical techniques used to interpret numerical data, rather than being a method of data collection itself. While quantitative analysis can certainly involve the use of collected data from various methods, it does not directly refer to how that data is gathered. In contrast, focus groups, surveys, and archival data are all distinct methods for collecting data.

Focus groups involve gathering a small group of people to discuss a specific topic, allowing for qualitative insights. Surveys are structured questionnaires designed to collect specific information from respondents. Archival data consists of existing records or documents that provide historical insights. Therefore, identifying quantitative analysis as the option that does not represent a data collection method highlights the understanding of how various methodologies differ in the realm of research.
