Introduction to Time Series Analysis and Forecasting

Much of the world's most valuable data—from stock prices and website traffic—is tracked over time. Understanding how to analyze these sequential datasets is a critical skill for any aspiring data professional. In this course, you will transition from a beginner to a confident analyst capable of identifying temporal patterns and preparing data for forecasting. You will learn how to deconstruct time-dependent data, handle seasonal variations, and apply foundational modeling techniques through clear, written explanations and practical data exercises. What you'll learn: • Understand key time series concepts including trend, seasonality, noise, and stationarity • Practice data preparation techniques specifically designed for temporal datasets • Apply modern analytical methods to resample, shift, and roll time series data • Evaluate autocorrelation to identify underlying patterns • Configure baseline forecasting models to predict future data points • Implement proper validation techniques to avoid look-ahead bias. The course begins with essential terminology and foundational concepts before moving into hands-on data manipulation. You will then explore exploratory data analysis and finish by constructing your first forecasting models. This text-only course is designed for beginners who want a structured, step-by-step introduction to temporal data analysis with no advanced prerequisites required.
