Quantitative analysis is commonly used in various fields, such as finance, economics, market research, and scientific research. It allows researchers and analysts to quantify relationships, identify patterns, and test hypotheses using objective and measurable data.
It’s important to note that quantitative analysis is just one aspect of data analysis. It is often complemented by qualitative analysis, which involves analyzing non-numerical data such as text or images.
By conducting quantitative analysis, you can gain a deeper understanding of the data, uncover relationships and trends, make informed decisions, and support evidence-based conclusions or recommendations.
