207 Non Random Sampling 1 Introduction

This video explains the crucial concept of non-random sampling in econometrics. It highlights how the fundamental assumption of a representative sample can be violated, leading to distorted conclusions. You'll learn why a sample being systematically different from the population is a data problem, not an estimation problem, and how it can affect the generalizability of your findings. Discover how this bias can lead to incorrect answers to your research questions, even with sound statistical methods. Visit AxiomTutoring.com and subscribe to @AxiomTutoringCourses.
