Which type of research uses numerical data to test predictions and find statistical relationships?

• A. Qualitative Research
• B. Quantitative Research
• C. Mixed Methods
• D. Propaganda Analysis

Answer: (B)

Using numerical data to test predictions and identify statistical relationships is the hallmark of quantitative research. This approach collects data in numeric form—through surveys with scaled responses, experiments, or existing statistics—and uses statistical analyses to determine whether ideas hold up across samples, measure the strength of relationships between variables, and generalize findings to a larger population. Qualitative research, in contrast, relies on non-numeric data like interviews and observations to explore meanings and patterns, while mixed methods combine both approaches. Propaganda analysis focuses on persuasive messaging and rhetoric, typically through qualitative analysis rather than systematic numerical testing.
