A data set is a collection of related information organized in a structured format, often in rows and columns. Each row typically represents a single record or observation, while each column contains a specific attribute or variable related to that record. Data sets can be used in various fields, including statistics, machine learning, and data analysis. Data sets can come in different forms, such as numerical data, categorical data, or text data. They can be small, like a list of students in a class, or large, like the data collected from social media platforms. Properly organized data sets are essential for drawing meaningful conclusions and insights.
