Data Sets
In Data Science, a data set is a collection of data that is organized in a specific way. It can be a structured or unstructured collection of data that is used for analysis, modeling, and machine learning. A data set can be a table, a spreadsheet, a database, or any other format that can be used to store and organize data. Data sets can be used to train machine learning models, to test hypotheses, to validate algorithms, and to make predictions. They can be collected from various sources such as surveys, experiments, sensors, social media, and web scraping. Data sets can be preprocessed, cleaned, and transformed to make them suitable for analysis. They can also be combined with other data sets to create more complex and comprehensive data sets.
