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.

10.2 Bivariate Analysis

Now that you have a good grasp of univariate analysis, which focuses on the study of a single variable, it's time to delve into the world of bivariate analysis. This method involves the examination of two variables to better comprehend the relationship that exists between them.

This is a vital process in data science, as it allows you to identify more complex patterns, correlations, and interdependencies in a multi-dimensional space. To put it simply, while univariate analysis provides insights about individual characters in a story, bivariate analysis helps to unveil the interactions and relationships between them, thus giving you a more complete picture of the narrative.

10.2.1 Scatter Plots

A scatter plot is an incredibly useful tool in your data visualization toolkit. It enables you to visually display the relationship between two variables in a clear and concise manner. By plotting data points against two axes, a scatter plot provides a quick and...
