M.S. in Statistics and Data Science

NA On Campus Masters Program

Yale University

Program Overview

The M.S. in Statistics and Data Science at Yale University provides advanced training in statistical theory, probability, machine learning and computational data analysis, preparing students to work with complex datasets and solve challenging analytical problems. Designed for students seeking careers in data science, quantitative research, technology, finance and other data-intensive fields, the program combines mathematical foundations with practical experience in statistical modelling, machine learning, big data and real-world data analysis.

Curriculum Structure

The M.S. in Statistics and Data Science requires students to complete 12 graduate-level term courses, with a three-semester residency requirement. Students develop a strong foundation in probability theory and statistical methods while selecting specialised courses in data science, computational techniques and application areas according to their academic interests and professional objectives.

First Semester – Building Foundations in Probability and Statistics

Students begin by strengthening their understanding of probability theory and statistical reasoning. Courses such as S&DS 5380 – Probability and Statistics, S&DS 5410 – Probability Theory, and S&DS 5420 – Theory of Statistics introduce essential mathematical concepts, probability distributions, statistical inference and the theoretical principles underlying data analysis.

Second Semester – Developing Data Science and Machine Learning Skills

Students progress towards more advanced analytical methods through courses such as S&DS 5630 – Multivariate Statistics, S&DS 5650 – Introductory Machine Learning, and S&DS 6650 – Intermediate Machine Learning. These subjects help students understand complex datasets, recognise patterns, develop predictive models and apply machine learning techniques to practical analytical problems. Students also explore computational subjects such as S&DS 5620 – Computational Tools for Data Science and S&DS 6620 – Statistical Computing.

Third Semester – Practical Data Analysis and Specialisation

Students strengthen their ability to apply statistical techniques to real-world problems through S&DS 6250 – Case Studies and S&DS 6260 – Practical Work. They can also select electives from areas such as Computer Science, Economics, Engineering and Applied Science, Linguistics and Biostatistics. Students interested in gaining additional practical experience may pursue an approved summer internship for course credit or an independent study, subject to departmental approval.

Note: Yale does not prescribe a fixed semester-by-semester course sequence. Students select courses in consultation with the Director of Graduate Studies (DGS), and the semesters above represent a suggested learning progression rather than an official study plan.

Focus Areas: Statistical Theory, Probability Theory, Statistical Inference, Machine Learning, Multivariate Statistics, Data Analysis, Statistical Computing, Big Data, Computational Statistics, Predictive Modelling, Data Mining, Optimization Techniques, Deep Learning, Statistical Learning Theory, Stochastic Processes.

Learning Outcomes: Apply probability theory and statistical principles to complex datasets, develop and evaluate statistical models, use machine learning techniques for predictive analysis, apply computational methods to large-scale data problems, interpret and communicate analytical findings, conduct practical data analysis, and use statistical reasoning to address problems across different application areas.

Professional Alignment (Accreditation): The M.S. in Statistics and Data Science is a graduate degree offered by Yale University's Department of Statistics and Data Science through the Graduate School of Arts and Sciences.

Employment and Salary Information: Yale's Department of Statistics and Data Science publishes examples of recent master's graduate placements but does not provide a dedicated employment rate or average salary specifically for the M.S. in Statistics and Data Science. Yale's broader undergraduate employment statistics should not be used as a substitute for programme-specific graduate outcomes.

Further Academic Progression: After completing the M.S. in Statistics and Data Science, graduates can consider pursuing a PhD in Statistics and Data Science, Applied Mathematics, Computer Science, Biostatistics, Economics or other related research disciplines. At Yale, students interested in continuing into the PhD programme must submit a completely new application, as admission to the terminal master's programme does not provide automatic progression. Graduates can also pursue research opportunities in machine learning, statistical theory, computational statistics, probability theory and data science.
