Data analysis is the process of examining, cleaning, and interpreting data to discover useful information and support decision-making. It helps you understand patterns, trends, and relationships within the data. For example, if a company wants to know which product is selling the most, data analysis can reveal sales trends across different months or regions. The process usually involves several steps—first collecting the data, then cleaning it to remove errors or missing values, followed by analyzing it using statistical methods or programming tools, and finally visualizing the results using charts or dashboards. Common tools used in data analysis include Excel, SQL, and Python with libraries like Pandas and Matplotlib, as well as visualization tools like Power BI and Tableau. In simple terms, data analysis turns raw numbers into meaningful insights that help businesses, researchers, and organizations make smarter and more informed decisions.
