Statistics is the science and art of prediction and explanation.
The mathematical foundation of statistics lies in the theory of probability, which is applied to problems of making inferences and decisions under uncertainty. Practical statistical analysis also uses a variety of computational techniques, methods of visualizing and exploring data, methods of seeking and establishing structure and trends in data, and a mode of questioning and reasoning that quantifies uncertainty. The Statistics program at Yale is a blend of the mathematical theory of probability and statistical inference, the philosophy of inference under uncertainty, computational techniques, the practice of data analysis, and statistical analysis applied to economics, biology, medicine, engineering, and other areas. Interested students are invited to consider the Statistics concentration within the Applied Mathematics major. This program requires four courses in Statistics in addition to the introductory courses in probability and the theory of statistics required of all Applied Mathematics majors.
