What is the difference between qualitative and quantitative research methods?

The distinction between qualitative and quantitative research methods is primarily rooted in the type of data they utilize and the purposes they serve. Qualitative methods focus on exploring phenomena through detailed, descriptive, and subjective data. This approach aims to gain a deeper understanding of experiences, thoughts, and feelings, often employing techniques such as interviews, focus groups, and open-ended surveys. It values context and the richness of human experience.

On the other hand, quantitative methods are designed to test hypotheses through numerical data and statistical analyses. This approach allows researchers to quantify behaviors, opinions, or variables, and to identify patterns or relationships among them. By relying on measurable data, quantitative methods can provide more objective results, enabling comparisons and generalizations across larger populations.

The other options presented do not accurately capture the essential characteristics that differentiate these two research methodologies. While some qualitative methods can indeed be conducted relatively quickly, this is not always the case and does not reflect a fundamental difference between the two approaches. Additionally, claiming that quantitative methods require less preparation overlooks the complexities often involved in designing robust quantitative studies. Finally, asserting that qualitative methods are only used in psychology is limiting, as they are widely applicable across various disciplines, including sociology, anthropology, education, and more.
