data analysis methodologies

Data analysis methodologies are structured approaches used to examine data, uncover patterns, and draw meaningful conclusions. Techniques include collecting relevant data, organizing it systematically, and applying methods like statistical testing or visualizations to interpret results. The goal is to transform raw information into insights that inform decisions or solve problems. Common steps involve cleaning data, exploring trends, and validating findings to ensure accuracy. These methodologies help businesses, researchers, and organizations make informed choices based on evidence rather than intuition alone.
