Qualitative vs. Quantitative — What's the Difference?
By Tayyaba Rehman — Updated on September 23, 2023
"Qualitative" refers to research or data focusing on non-numerical characteristics, such as color, texture, or type. "Quantitative" refers to research or data that can be measured numerically, such as height, weight, or speed.

Key Differences
"Qualitative" and "Quantitative" are terms often used in the context of research, data collection, and analysis. Qualitative data explores characteristics that can be observed but not measured. These characteristics often include attributes like texture, color, or taste. On the other hand, quantitative data can be measured and expressed in numbers, such as percentages, scales, or counts.
Qualitative research generally aims to understand underlying reasons, opinions, or motivations and often relies on methods like open-ended surveys and interviews. It's more concerned with the "how" and "why" of things. Quantitative research aims for statistical analysis, usually through structured methods like questionnaires or polling, focusing more on the "how much" or "how many."
While both qualitative and quantitative data can provide valuable insights, they are usually best when used together. Qualitative research can offer context for quantitative data. For instance, qualitative data can explain why a particular set of quantitative results came to be. Conversely, quantitative data can provide a broad overview that qualitative research can then delve into for more detail.
In summary, qualitative and quantitative approaches serve different purposes and are often complementary. Qualitative data gives context and explores the intricacies of a subject, while quantitative data provides the numerical metrics that can be analyzed for trends and statistics.
