Yes, I agree that classified data is better than raw data. Raw data is highly disorganised, often very large, and cumbersome to handle. Drawing meaningful conclusions from raw data is a tedious task because it does not yield to statistical methods easily.

Classification brings order to the data and makes it comprehensible. When facts of similar characteristics are placed in the same class, it enables one to locate them easily, make comparisons, and draw inferences without any difficulty.

Classification saves our valuable time and effort. Proper organisation and presentation of data through classification makes systematic statistical analysis possible. Therefore, classified data is more useful and efficient than raw data.
