What is the primary focus of quantitative research?

The primary focus of quantitative research is on measuring and analyzing numerical data. This approach involves collecting data that can be quantified, allowing researchers to apply statistical methods to assess relationships, test hypotheses, and make predictions. Quantitative research aims to obtain objective measurements that can be generalized to larger populations, making it essential for examining trends, making comparisons, and establishing patterns of behavior.

In contrast, the other options address different aspects of research. Understanding human behavior qualitatively emphasizes exploration and interpretation, typically focusing on experiences and meanings rather than numerical data. Developing theoretical concepts generally pertains to qualitative research, which often seeks to build theories or insights based on collected data. Conducting in-depth interviews represents a qualitative research method that aims to gather detailed and rich information from individuals, again differing from the quantitative focus on numbers and statistical analysis.
