Correct Answer Explanation
The schoolbook analogy illustrates that classification saves time — when books are arranged by subject, finding a specific book requires searching only in the relevant group.
Key Points:
- Without classification: search the entire collection to find one book.
- With classification (by subject): go directly to the relevant group.
- Similarly, without data classification: tedious to extract any information from raw data.
- With classification: easy to locate, compare, and draw inferences.
- The classification criteria must match the purpose (books by subject, or by author, or by year of publication).
