What This Document Is
This is a midterm exam (Version 6A) for Duke University’s Econometrics (ECON 104) course, taught by Professor Andrew Patton in Spring 2021. It assesses students’ understanding of statistical foundations relevant to econometrics and data science. The exam is designed to be completed within a one-hour timeframe and is “open book,” allowing the use of textbooks, notes, and computational tools like calculators or Excel.
Why This Document Matters
This exam is crucial for students enrolled in ECON 104 to gauge their comprehension of the course material covered up to March 4, 2021. It serves as a significant component of their overall grade and provides valuable practice applying econometric principles. Students preparing for similar econometrics courses, or seeking a challenging practice exam in probability and statistics, may also find this resource useful for self-assessment.
Common Limitations or Challenges
This document is a past exam and does not include solutions. It’s designed to test existing knowledge, not to teach new concepts. While the open-book format allows for reference materials, successfully completing the exam requires a solid understanding of the underlying principles and the ability to apply them to novel problems. It does not offer instruction or explanations of the concepts tested.
