The field of Statistics aims to interpret large data sets that contain random variation. Baseball is a game that contains a high degree of randomness, and because professional baseball has been played since the 19th century, a large amount of data has been collected about players' performance. In this class we examine key concepts in Statistics using baseball as a motivating example, and students will learn how to use the R programming language to analyze data. Assignments will consist of weekly problem sets, two class presentations, and a short final project. By taking this class students will develop an understanding of key statistical concepts that will be useful for interpreting data from many fields.
