A dataset is a collection of related information organized in a structured way, often in tables or spreadsheets. Each entry in a dataset typically includes various attributes or features, which can be numbers, text, or dates. For example, a dataset about students might include their names, ages, and grades, making it easy to analyze their performance. Datasets are essential in fields like data science, machine learning, and statistics, as they provide the raw material needed for analysis and decision-making. By examining datasets, researchers and analysts can uncover patterns, make predictions, and gain insights that help solve real-world problems.
