Quantitative data is fundamentally characterized by its ability to measure information using numerical values. This type of data is focused on quantities and can be represented mathematically, allowing for various statistical analyses. For instance, when measuring height, weight, temperature, or any other measurable attribute, the results are expressed as numbers, making it easy to perform calculations and comparisons.

In contrast, qualitative data involves descriptive attributes or characteristics that are not inherently numerical. It captures information about qualities, such as opinions, experiences, or categories, making it more subjective in nature. While qualitative data may sometimes be coded or categorized in ways that allow for limited numerical representation, it does not rely on numerical values in the same way that quantitative data does. Understanding the distinction between these two types of data is essential for effective analysis in various contexts.
