Data Exploration and Cleaning with pandas

Raw data is rarely ready for analysis or modeling. To build accurate machine learning models, you must first know how to identify errors, handle missing values, and structure your datasets correctly. This text-based course guides you through the entire data preparation pipeline, turning messy real-world data into high-quality assets. You will start by understanding foundational data quality concepts and key terminology before moving into hands-on data manipulation. Learn to profile datasets, detect anomalies, resolve formatting issues, and handle missing values efficiently using pandas and modern Python practices. What you'll learn: Understand core data quality metrics and the lifecycle of data preparation; Identify and handle missing, duplicate, and outlier data points; Apply modern pandas techniques to clean, filter, and transform messy datasets; Structure and format variables correctly for downstream machine learning algorithms; Validate data integrity using modern schema testing and verification practices. The course flows logically from basic data exploration concepts to advanced cleaning techniques, ensuring you build confidence with every chapter. This program is designed specifically for beginners and aspiring data professionals, requiring only a basic familiarity with Python.
