• 📊 Positive economics involves models without value judgments, while normative economics involves value judgments.
• 🔬 Economics is divided into microeconomics (individual agents and markets) and macroeconomics (entire economy).
• 📈 Econometrics is a branch of statistics focused on analyzing real-world economic data.
• 🌍 Economists study a wide range of topics, including crime, war, family, religion, culture, politics, law, and genetics.
