Description: The ‘Data Population’ refers to the complete set of data from which a sample can be extracted for analysis. This concept is fundamental in the field of statistics and data analysis, as it allows researchers and analysts to understand the context and breadth of the information they are handling. The data population can range from a limited set of records to large volumes of information, such as those found in data lakes. In the context of machine learning and artificial intelligence, the data population is crucial for training models, as the quality and representativeness of the data directly influence the accuracy and effectiveness of the generated models. Clearly identifying and defining the data population is essential to ensure that the selected samples are representative and that the results obtained are valid and applicable to real-world situations. Furthermore, the data population must be managed properly to ensure its integrity and accessibility, which is especially relevant in environments where large amounts of data are stored in their original format for later analysis.
