What is the relationship between qualitative data and quantitative data?

The correct answer highlights the essential relationship between qualitative data and quantitative data. Qualitative data, which is often descriptive and exploratory in nature, provides context that enhances the understanding of quantitative findings. This means that when researchers or analysts collect numerical data through surveys or experiments, the qualitative insights help explain the "why" behind the numbers. For example, if a survey reveals a significant drop in employee satisfaction scores, qualitative data from open-ended responses can shed light on specific issues or themes driving that decrease, such as management practices or workplace culture.

This interplay allows for a more comprehensive analysis and interpretation of data. While quantitative data can illustrate trends or patterns, qualitative data enriches those findings by adding depth and perspective, enabling decision-makers to grasp the underlying factors influencing the numerical results. This relationship illustrates the complementarity of the two data types in effective data analysis and interpretation.
