preprocessing

In Class 9 Artificial Intelligence, the topic “Preprocessing” introduces students to the important Data Literacy steps used to make raw data reliable and ready for analysis. Students learn how to identify and handle missing values, remove duplicate or inconsistent entries, correct errors, organize data into suitable formats, and represent information clearly. They also explore why clean, well-structured data improves the accuracy and fairness of observations, patterns, and AI-based decisions.
