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.

8.2 Types of Data

8.2.1 Numerical Data

Numerical data is an essential element of scientific research and represents quantitative measurements of various phenomena. It is divided into two main types: discrete and continuous data. Discrete data refers to data that can only take certain specific values and is often obtained by counting.

For example, the number of cars in a parking lot can be counted, and the result is a discrete number. On the other hand, continuous data refers to data that can take any value within a specific range and can be measured using a scale. For example, the weight of an object can be measured using a scale, and the result is continuous data. Both types of data are important in scientific research and can provide valuable insights into various phenomena.

Discrete Data

This type of data consists of distinct and separate values that cannot be subdivided into smaller units. It is often composed of counts of things that are readily measurable. A good example of...
