Qualitative vs. Quantitative: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on January 8, 2024
Qualitative research focuses on understanding characteristics and descriptions, often through observation and interviews, while quantitative research involves numerical data and statistical analysis.
Key Differences
Qualitative research is exploratory, aiming to understand underlying reasons and motivations, in contrast to quantitative research, which seeks to quantify data and generalize results from sample to population.
In qualitative research, data collection includes interviews, focus groups, and observations, providing in-depth insights, whereas quantitative research uses structured tools like surveys and questionnaires for data collection.
Qualitative analysis is interpretive, focusing on themes and patterns in non-numerical data, while quantitative analysis relies on statistical methods and mathematical calculations.
The outcome of qualitative research is more descriptive, capturing the complexity of human behavior, in contrast to quantitative research that results in numerical outputs and generalizable findings.
In qualitative research, the researcher often has a closer, more subjective relationship with the data, unlike in quantitative research, where the researcher maintains distance and objectivity.
