Answer:
d. quantitative
Explanation:
When a researcher uses numerical analysis, she is engaged in quantitative research.
Numerical data must be gathered, analyzed, and interpreted in quantitative research. It focuses on producing quantitative or statistical data that can be measured, quantified, and analyzed. In this instance, the researcher is using numerical analysis, which denotes the analysis and interpretation of data using mathematical and statistical methods.Large-scale data processing and the use of mathematical models, algorithms, and statistical techniques are frequent components of numerical analysis. The researcher may perform calculations, visualizations, and hypothesis testing using tools like statistical software or programming languages.
In order to understand the research topic more objectively and methodically, the researcher uses numerical analysis to quantify relationships, patterns, and trends within the data. This strategy is especially helpful in disciplines like economics, engineering, computer science, and the natural sciences, where the study and analysis of phenomena heavily relies on numerical data.
