data analysis methods

Data analysis involves examining information to uncover patterns, relationships, and insights. It includes collecting relevant data, organizing it for clarity, and then applying techniques like summarizing data to see overall trends, comparing different groups to find differences, and using calculations or charts to visualize patterns. The goal is to turn raw data into meaningful knowledge that helps in making informed decisions, solving problems, or understanding a situation better. Good data analysis is systematic, accurate, and tailored to answer specific questions or objectives.
