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.

Data Collection and Preprocessing

Now that you're familiar with the problem we aim to solve, let's get our hands a little dirty with data! Data collection and preprocessing are essential steps that lay the foundation for any machine learning project. If you think of machine learning as cooking, then data is your key ingredient. The better the quality, the tastier the result!

Data Collection

In a real-world scenario, data collection would involve gathering data from various sources like databases, logs, or external APIs. For our capstone project, we've provided a dataset named product_interactions.csv. This file contains interactions of users with different products, as we discussed in the Problem Statement section.

You can read this dataset into a DataFrame using the following code snippet:

import pandas as pd

 

# Read the CSV file into a DataFrame

df = pd.read_csv('product_interactions.csv')

 

# Show the first few rows of the DataFrame

df.head()
