data analysis techniques

Data analysis techniques involve systematically examining and interpreting data to extract meaningful insights. Common methods include statistical analysis, which uses mathematical tools to summarize data trends; visualization, which presents data through charts or graphs for easier understanding; and descriptive analysis, which outlines basic features of data. More advanced techniques like predictive analysis forecast future trends based on historical data. These methods help identify patterns, make informed decisions, and derive actionable knowledge from complex information, aiding in various fields such as business, science, and social research.
