Overview of Statistics
The curriculum in liberal arts and sciences with a major in statistics is designed to prepare students for (1) statistics positions in business, industry or commerce, nonprofit institutions, and in state or federal government; and (2) graduate study in statistics. Positions include the following types of work: statistical design, data visualization, analysis and interpretation of experiments and surveys; data processing and analysis using modern computation facilities and statistical computing systems; application of statistical principles and methods in commercial areas such as finance, insurance, industrial research, technology, marketing, manufacturing, sports analytics, quality control, and nonprofit organizations, such as institutions involved in health care or medical research.
Given the application of statistical work to a broad range of fields, students majoring in statistics often obtain at least a minor in a field of application. Some common minors earned by statistics majors are Economics, General Business, and Mathematics. Students preparing for positions in data analysis should consider a minor or certificate in Data Science. Students preparing for a career in the field of actuarial science should consider a certificate in Actuarial Science. Students intending to pursue graduate study in Statistics are strongly advised to complete at least a minor in Mathematics including credit in MATH 4140 Analysis I.
Many Statistics majors earn an additional major or degree in a field of application or in Mathematics. Your academic advisor can assist you in developing your course of study including other majors.
Student Learning Outcomes
Students completing the undergraduate degree in statistics should have a broad understanding of the discipline of statistics. Upon graduation, students should be able to:

All credits used to meet the minor requirements may also be used to satisfy the credit requirement for graduation and to meet credit requirements in courses numbered 3000 or above.
Courses used to complete the minor may not be taken on a pass-not pass basis.
The Statistics Undergraduate Minor is an LAS Minor. In addition to University polices governing minors, LAS minors require at least 6 credits in courses numbered 3000 and above, with a grade of C or higher.
Graduate Study
The department offers graduate programs leading to the Master of Applied Statistics degree, and the Master of Science (M.S.) and the Doctor of Philosophy (Ph.D.) degrees with a major in Statistics.
Graduates of the Master of Applied Statistics program develop a strong foundation in statistical applications, learning to correctly use and interpret the most frequently employed classical and modern methods in statistics. The students will gain skills in selecting appropriate techniques for data-driven problems, explaining theoretical foundations of classical and modern statistical methods, and effectively communicating statistical results to all stakeholders. Students will also learn to use modern statistical computing technologies, and to apply machine learning and artificial intelligence to enhance insights from data. Students complete a minimum of 30 semester credits, including statistical consulting coursework and credit for statistical work experience through an internship or current employer.
Graduates of the M.S. program have studied basic statistical theory and methods. Elective courses in the M.S. program provide an opportunity for students to emphasize particular areas of application in their program. Students complete a minimum of 34 semester credits, including work on a capstone project resulting in a written creative component under the direction of an individual major professor and defended in a final oral examination.
Graduates of the Ph.D. program have demonstrated mastery of basic statistical theory and methods, studied advanced statistical theory and methods, and have demonstrated the ability to conduct independent research resulting in an original contribution to the discipline. Candidates for the Ph.D. degree in Statistics complete a minimum of 72 semester credits, including at least 18 credits given for research activity, pass an oral preliminary examination, and submit a written dissertation containing original research that is defended in a final oral examination. Dissertation research is typically conducted in close collaboration with a major professor and usually results in publishable material. The department does not offer specific program tracks or areas of emphasis, but the diversity of elective courses and research areas of faculty allow students to tailor their individual programs to reflect areas of particular interest.
The Ph.D. degree is also offered as a co-major with other graduate programs. Graduates of co-major Ph.D. programs in Statistics and an applied scientific discipline have demonstrated mastery of basic statistical theory and methods and have studied advanced statistical methodology. Students complete a minimum of 72 semester credits for courses in statistics and the chosen scientific discipline. Students conduct research that is a combination of statistical methodology and the scientific discipline. Co-major professors work with the student to prepare for an oral preliminary examination and to conduct research leading to a single dissertation project, defended in a final oral examination, that produces an original contribution to at least one of the two disciplines.
Graduates of co-major Ph.D. programs in statistics and an area of theoretical mathematics have demonstrated mastery of basic statistical theory and methods and have studied advanced statistical theory. Students complete a minimum of 72 semester credits for courses in statistics and the other discipline. Co-major professors work with the student to prepare for an oral preliminary examination and to conduct research leading to a single dissertation project, defended in a final oral examination, that makes an original contribution at the interface of statistical theory and a sub-discipline of mathematics.
Graduate work leading to a minor in statistics is available for students majoring in other programs, at both the M.S. and Ph.D. levels.
The department participates in inter-disciplinary graduate programs in Bioinformatics and Computational Biology, Ecology and Evolutionary Biology, Genetics, Human Computer Interaction, Nutritional Sciences, and Wind Energy Science, Engineering, and Policy.
