Research tools are designed to collect different types of data. Qualitative data is non-numerical, descriptive, and aims to provide in-depth understanding of experiences, perceptions, and meanings. Quantitative data, conversely, is numerical and focuses on measurable aspects.
The correct answer is Interview. Interviews, especially open-ended ones, allow researchers to gather rich, detailed narratives and explore participants' perspectives in depth, which are hallmarks of qualitative data. The other options, MCQ (Multiple Choice Questions), Test (in its typical standardized form), and Rating scale, primarily generate quantitative data. MCQs and tests yield scores, while rating scales produce numerical values that are then statistically analyzed, making them tools for quantitative research.
