Mastering Data Exploration and Preprocessing with Python and SQL

This course is designed to provide you with a comprehensive understanding of how to effectively explore and preprocess data using Python and SQL. Through hands-on exercises and practical examples, you will learn various techniques to clean, transform, and analyze data, enabling you to derive valuable insights and make informed decisions.

• Gain a solid understanding of the Exploratory Data Analysis (EDA) process and its significance in data analysis.
• Learn how to load, manipulate, and clean data using Python libraries such as Pandas and NumPy.
• Explore data visually using Matplotlib and Seaborn to uncover patterns, trends, and outliers.
• Understand data preprocessing techniques like handling missing values, dealing with categorical data, and feature scaling.
• Apply advanced techniques like dimensionality reduction and feature engineering to enhance data quality and model performance.

• Basic knowledge of Python programming language.
• Familiarity with fundamental concepts of data analysis and statistics.
• Understanding of SQL fundamentals would be beneficial but not mandatory.
