What distinguishes quantitative analysis from qualitative analysis?

The correct choice emphasizes that quantitative analysis is characterized by the use of numerical data. This type of analysis allows researchers to measure variables and analyze data through statistical methods, leading to conclusions that can be generalized across larger populations. Quantitative analysis is often employed in research to assess relationships, test hypotheses, and quantify behaviors or opinions, ultimately providing a clear, objective view of the data involved.

In contrast, qualitative analysis typically focuses on non-numerical data, such as words, themes, and concepts. This approach seeks to understand deeper meanings, experiences, and contexts rather than relying on numbers. Thus, the distinction lies in the methodologies and types of data utilized, making the emphasis on numerical data a defining feature of quantitative analysis. Understanding this distinction is crucial for conducting effective research and choosing the appropriate analytical method for specific research questions.
