What are the key differences between quantitative and qualitative research methods?

The key differences between quantitative and qualitative research methods lie in their approaches, data collection, analysis, and the type of information they seek to uncover.

Quantitative research is a systematic and structured approach that focuses on numerical data and statistical analysis. It aims to measure and quantify phenomena, often using surveys, experiments, or existing datasets. This method emphasizes objectivity, generalizability, and the ability to make predictions or draw conclusions based on statistical evidence. It typically involves large sample sizes and employs statistical techniques to analyze data.

On the other hand, qualitative research is a more subjective and interpretive approach that seeks to understand the meaning and context of social phenomena. It relies on non-numerical data, such as interviews, observations, and textual analysis, to explore individuals' experiences, beliefs, and behaviors. Qualitative research emphasizes in-depth understanding, contextuality, and the exploration of complex social processes. It often involves smaller sample sizes and employs techniques like thematic analysis or grounded theory to analyze data.

While quantitative research aims to establish causal relationships and test hypotheses, qualitative research focuses on generating rich descriptions, exploring social phenomena from multiple perspectives, and uncovering new insights. Both methods have their strengths and limitations, and researchers often choose between them based on their research questions, objectives, and the nature of the phenomenon being studied.
