Columbia University

The Department offers several introductory courses.  Students interested in statistical concepts, who plan on consuming, but not creating statistics, should take STAT UN1001 INTRO TO STATISTICAL REASONING.  The course is designed for students who have taken a pre-calculus course, and the focus is on general principles.  It is suitable for students seeking to satisfy the Barnard quantitative reasoning requirements.  Students seeking an introduction to applied statistics should take STAT UN1101 Introduction to Statistics.  The course is designed for students who have some mathematical maturity, but who may not have taken a course in calculus, and the focus is on the elements of data analysis.  It is recommended for pre-med students, and students contemplating the concentration in statistics.  Students seeking a foundation for further study of probability theory and statistical theory and methods should take STAT UN1201 Calculus-Based Introduction to Statistics.   The course is designed for students who have taken a semester of college calculus or the equivalent, and the focus is on preparation for a mathematical study of probability and statistics.   It is recommended for students seeking to complete the prerequisite for econometrics, and for students contemplating the major in statistics.  Students seeking a one-semester calculus-based survey of probability theory and statistical theory and methods should take STAT GU4001 INTRODUCTION TO PROBABILITY AND STATISTICS.  This course is designed for students who have taken calculus, and is meant as a terminal course.  It provides a somewhat abridged version of the more demanding sequence STAT GU4203 PROBABILITY THEORY and STAT GU4204 Statistical Inference.  While some mathematically mature students take the more demanding sequence as an introduction to the field, it is generally recommended that students prepare for the sequence by taking STAT UN1201 Calculus-Based Introduction to Statistics.
