What is quantitative data primarily based on?

Quantitative data is primarily derived from exact numbers and counts, which distinguishes it from qualitative data that is descriptive and often derived from subjective experiences or narratives. In quantitative research, data is collected in a manner that allows for statistical analysis, making it inherently structured and focused on measurement. This form of data can be used to validate hypotheses, identify trends, and establish relationships between variables using mathematical techniques.

The emphasis on numerical data enables researchers to perform calculations that yield insightful statistics, such as averages, percentages, and correlations. This rigorous approach provides a solid foundation for making data-driven decisions and drawing objective conclusions from research findings. In contrast, the other options focus on qualitative aspects, such as narratives or visual observations, which do not provide the same level of quantifiable evidence needed to analyze and interpret data in a numerical context.
