Introduction to Econometrics: Finding Cause and Effect in Data

In a world flooded with data, predicting trends is no longer enough. To make truly impactful decisions, you must understand whether one factor actually causes another, or if they are merely correlated. This text-based course introduces you to the core principles of econometrics, the science of identifying causal relationships within economic and social data. You will move beyond standard predictive machine learning to master the analytical frameworks needed to eliminate bias, select the right variables, and draw credible conclusions that drive policy and business strategy. What you'll learn: 1. Understand the fundamental difference between correlation, prediction, and causal inference. 2. Apply classical linear regression models to isolate the impact of specific variables. 3. Identify and mitigate common sources of bias, such as omitted variable bias and selection bias. 4. Explore modern causal frameworks, including Directed Acyclic Graphs (DAGs) and the potential outcomes model. 5. Analyze real-world scenarios using instrumental variables, difference-in-differences, and regression discontinuity designs. 6. Interpret statistical outputs with a focus on economic intuition rather than pure mathematical abstraction. We begin by establishing essential definitions and economic theory, ensuring you have a strong theoretical foundation. From there, you will read through step-by-step written analyses, exploring how to structure econometric models and address real-world data limitations. This course is designed for aspiring data analysts, economists, and curious beginners who want to understand the mechanics of cause and effect. No prior advanced statistical background is required.
