What are the two main types of research techniques employed for data accumulation?

The focus on qualitative and quantitative research as the main types of research techniques is correct because these two approaches address distinct aspects of data accumulation. Qualitative research is centered around understanding concepts, thoughts, or experiences through methods like interviews, focus groups, and open-ended surveys. It provides deeper insight into the motivations, feelings, and behaviors of participants, allowing researchers to explore complex issues that cannot be quantified easily.

On the other hand, quantitative research revolves around numerical data and statistical analysis. It employs methods such as surveys with closed-ended questions or experiments where results can be quantified and measured. This type of research aims to identify patterns or correlations and is often used to test hypotheses.

Both research methodologies complement each other, offering a comprehensive view of a research question by combining rich, detailed narratives with numerical data that can support findings with statistical evidence. This integrative approach allows for a well-rounded understanding of the research problem being investigated.

In contrast, the other options represent different classifications or aspects of research but do not capture the overarching qualitative versus quantitative divide. For instance, exploratory and descriptive research refer to specific research purposes, while experimental and observational research pertains to different research designs within broader methodologies. Primary and secondary research distinguish between original data collection and the use of previously collected data
