What approach does quantitative data primarily use?

Quantitative data primarily relies on numerical measurement and statistics because it aims to quantify variables and analyze relationships among them. This approach involves collecting data that can be counted or measured, which is then represented with numbers. Through statistical methods, researchers can conduct various analyses, such as calculating averages, variances, or relationships through regression analysis.

This use of numbers allows for precise measurements, facilitates comparison between different datasets, and supports hypothesis testing. Consequently, quantitative data is invaluable in fields where objective analysis is necessary, such as in many scientific, social science, and business applications. In contrast, the other options, such as descriptive analysis, narrative storytelling, and qualitative methodology, do not emphasize numerical frameworks, making them less suitable for the primary focus of quantitative data.
