Final answer:
Quantitative research focuses on generating numerical data and statistical analysis, not on the 'why,' which is the domain of qualitative research. It is primarily used in case studies and social sciences to identify trends and patterns. The correct option is B.
Step-by-step explanation:
Quantitative research is focused on generating numerical data and statistical analyses to understand phenomena and usually addresses questions of 'how many' or 'how much.' In contrast, qualitative research seeks to understand the meaning, characteristics, and descriptions of phenomena, often asking the question 'why.' Therefore, the statement 'Quantitative research focuses on the "why"' is False.
Social sciences often use quantitative data to identify patterns or trends through methods like surveys, while case studies in health or other fields rely on it to make data-driven conclusions. However, qualitative research typically provides the context necessary to understand the reasons behind certain behaviors or trends and is characterized by in-depth interviews, focus groups, and content analysis.
