Numerical data is represented by?

Numerical data is fundamentally represented by numbers, which is why the correct choice is the representation of numerical data with numbers themselves. This type of data is quantitative in nature and allows for mathematical operations and statistical analysis to be performed.

In various fields, numerical data can take forms such as integers, decimals, and fractions, enabling precise measurement and calculation. This allows businesses and researchers to analyze trends, perform calculations, and apply statistical methods effectively.

On the contrary, textual descriptions, words and symbols, and qualitative categories represent non-numerical data or data that is primarily qualitative. Textual descriptions provide context or insights but lack the quantitative aspect necessary for numerical analysis. Similarly, words and symbols are often used to convey information or ideas rather than numerical values. Qualitative categories are classifications based on characteristics or attributes rather than numeric values and do not support quantitative analysis, making them distinctly different from numerical data.
