What type of data is typically gathered through interviews and is rich in detail?

The correct choice is qualitative data. This type of data is characterized by its richness and depth, often providing insights into participants' thoughts, feelings, and experiences. Through interviews, researchers can gather descriptive information that captures the complexity of human behavior, allowing for a nuanced understanding of the topic being studied. Qualitative data is non-numeric and often involves open-ended questions that encourage detailed responses, making it invaluable in fields like psychology where understanding context and personal perspective is essential.

In contrast, quantitative data refers to information that can be measured and expressed numerically, often relying on structured formats such as surveys with closed-ended questions. Statistical data specifically pertains to data that can be analyzed through statistical methods, which usually involves quantifying information for comparative purposes. Numerical data is a form of quantitative data that deals specifically with numbers. While all these types of data have their merits, qualitative data stands out for its ability to provide rich narratives and detailed insights gathered directly from personal accounts during interviews.
