Description: Numerical transformation is the process of converting numerical data into a different format or scale for analysis. This process is fundamental in data preprocessing, as it allows the data to be more understandable and useful for analysis algorithms. Transformation can include techniques such as normalization, which adjusts values to a specific range, or standardization, which transforms data to have a mean of zero and a standard deviation of one. These techniques are essential for improving data quality and facilitating interpretation. Additionally, numerical transformation helps mitigate issues such as scale heterogeneity, where different variables may have vastly different value ranges, potentially affecting the performance of analytical models. In summary, numerical transformation is a critical stage in the data analysis workflow, ensuring that the data is suitable for modeling and decision-making.
