Data Analysis and Machine Learning with Python, Pandas, and NumPy

Data is the backbone of modern decision-making, but raw data is rarely ready for analysis. To turn messy datasets into actionable insights, you need to master the core libraries of the Python data science ecosystem. This text-based course takes you from absolute beginner to confidently manipulating, visualizing, and modeling data. You will start by understanding foundational data concepts and key terminology before moving on to write clean, efficient Python code for real-world data tasks. By the end of this course, you will be able to clean complex datasets, perform exploratory data analysis, create clear visualizations, and build basic machine learning pipelines. What you'll learn: - Understand the core terminology of data science, including data structures, arrays, and tidy data principles. - Manipulate and clean tabular data using Pandas dataframes, indexing, and modern method chaining. - Perform numerical computations and array operations efficiently with NumPy. - Create informative data visualizations using Matplotlib and Seaborn to uncover hidden patterns. - Prepare data and build foundational machine learning models using Scikit-Learn pipelines. - Analyze time-series data and handle missing values using industry-standard techniques. The course begins with foundational concepts of data structures and statistical terminology before guiding you through step-by-step written explanations of data wrangling, visualization, and basic predictive modeling. You will read through clear code examples and apply your knowledge through practical written exercises designed to reinforce your learning. This course is designed for beginners who are new to data science and analytics. No prior experience with Pandas or machine learning is required, though a basic familiarity with Python variables and loops is helpful.
