Data Analysis Foundations with Python

By: Cuantum Technologies LLC

Overview of this book

Embark on a comprehensive journey through data analysis with Python. Begin with an introduction to data analysis and Python, setting a strong foundation before delving into Python programming basics. Learn to set up your data analysis environment, ensuring you have the necessary tools and libraries at your fingertips. As you progress, gain proficiency in NumPy for numerical operations and Pandas for data manipulation, mastering the skills to handle and transform data efficiently. Proceed to data visualization with Matplotlib and Seaborn, where you'll create insightful visualizations to uncover patterns and trends. Understand the core principles of exploratory data analysis (EDA) and data preprocessing, preparing your data for robust analysis. Explore probability theory and hypothesis testing to make data-driven conclusions and get introduced to the fundamentals of machine learning. Delve into supervised and unsupervised learning techniques, laying the groundwork for predictive modeling. To solidify your knowledge, engage with two practical case studies: sales data analysis and social media sentiment analysis. These real-world applications will demonstrate best practices and provide valuable tips for your data analysis projects.

1.1 Data Collection

Before we can commence with the analysis phase of our data science project, it is imperative that we first gather our raw materials which, in this case, is data. Data is the fundamental building block of any data science project and can be sourced from a variety of sources depending on the project requirements.

However, for this specific project, we will need to scrape customer reviews from the website of an online retailer. It is important to note that web scraping may not be allowed by some websites' terms of service, hence it is crucial that you ensure you are aware of these terms before proceeding with the data collection process.

Furthermore, it is worth mentioning that the process of web scraping may require specialized tools and techniques that are beyond the scope of this document. Therefore, it is recommended that you research and familiarize yourself with the necessary tools and techniques before proceeding with the data collection process.
