A dataset is a structured collection of data, often organized in a tabular format such as spreadsheets or CSV files, where information is arranged in rows and columns. Datasets can encompass various types of data, including numerical, textual, images, videos, and audio files. They serve as the foundation for data analysis, machine learning, and research across multiple domains. Datasets can be created through various methods, including manual collection, automated processes, or by aggregating existing data from different sources. Understanding datasets is crucial for data scientists and researchers as they form the basis for deriving insights and making informed decisions.
