Which research approach relies on numerical data such as ratings and scales for statistical analysis?

• A. Qualitative Research
• B. Primary Research
• C. Field Research
• D. Quantitative Research

Answer: (D)

This question tests understanding of data types used in research and how they enable analysis. Quantitative research relies on numerical data—like ratings and scales—that can be analyzed statistically to identify patterns, relationships, and differences. When you collect numbers through instruments such as Likert scales or numeric ratings, you can perform calculations, run tests, and generalize findings to a larger population. In contrast, qualitative research uses non-numeric data such as interview transcripts or observations, focusing on meaning and context rather than statistics. The other terms describe data sources or settings rather than the data type and analysis method. So the approach described is quantitative research.
