Data Science 🐍 Prepare Data

This video tutorial covers the essentials of preparing data for data science projects. It begins with an introduction to data preparation, emphasizing the importance of conditioning raw data. The tutorial then explores techniques for visualizing and cleaning data, including handling outliers using tools like Numpy and Pandas. It further delves into methods for identifying and removing outliers through statistical tests and conditions. Finally, the video discusses the significance of scaling data and splitting it into training and testing sets to ensure effective machine learning model development.
