Lesson 3: Feature Engineering

Lesson 3: Feature Engineering

Feature engineering is the process of creating new useful columns from existing data to improve analysis and understanding.

In this project, we created a new column called Performance_Change, calculated as:

Exam_Score − Previous_Scores

This helped us:

Identify whether students improved or declined.
Group students into performance categories.
Analyze factors responsible for score changes.
Prepare structured input for machine learning.

Feature engineering helps transform raw data into more meaningful analytical insights.
