Description: Value filtering is the process of removing unwanted values from a dataset based on specified criteria. This procedure is fundamental in data preprocessing, as it ensures that subsequent analyses are conducted on clean and relevant information. Unwanted values may include erroneous data, duplicates, or those that do not meet specific quality criteria. By applying value filtering, the accuracy of analytical models is improved, and the quality of the results obtained is optimized. This process can be performed manually or automatically, using software tools that allow for the establishment of specific rules for identifying and removing problematic data. The importance of value filtering lies in its ability to reduce noise in the data, which in turn facilitates informed decision-making and the generation of meaningful insights from the processed data.
