Data sampling is the process of selecting a representative subset of data from a larger dataset. This is a crucial step in the Data Mining process as it helps to reduce the computational complexity, increase efficiency, and avoid overfitting. By selecting a representative sample, we can ensure that our analysis is accurate and reliable. Once the sample is selected, we move on to the other steps such as data preparation, model construction, and model assessment.
