Degrees Offered

  • Master of Science

Nature of the Program

The Department of Statistics offers a Master of Science (M.S.) in Statistics. The M.S. degree is intended to qualify the student to assume a professional role in educational, industrial, or governmental research projects; to teach in a college; or to undertake advanced training toward a doctorate in statistics or one of the quantitative fields of science.

Because many students receive baccalaureate degrees from colleges that do not offer undergraduate programs in statistics, and because historically statistics has been primarily a field of graduate education, a student does not need a degree in statistics to enter the degree program. A good background in mathematics, science, or engineering is reasonable preparation for graduate work in statistics.

The Department of Statistics also participates in the Combinatorial Computing and Discrete Mathematics (CCDM) Area of Emphasis within the Computer and Information Science Ph.D. Program or the Mathematics Ph.D. Program.

The Department of Statistics offers a Certificate in Applied Statistics for professionals or students who want to take applied statistics courses to enhance their quantitative skills and job opportunities.

Admissions and Prerequisites for Master of Science in Statistics

Students are expected to know the material contained in the following courses or areas upon admission to the program. Otherwise, these deficiencies must be removed as early as possible in the student’s degree program under the terms specified by the Admissions and Standards Committee.

  • Single and multivariable calculus (MATH 155, MATH 156, MATH 251, or equivalent)
  • Linear or matrix algebra (MATH 441 or equivalent)
  • Probability and statistics (STAT 215 or equivalent)
  • Knowledge of a high-level programming language

Admissions and Prerequisites for the Certificate in Applied Statistics

Admission to the Certificate of Applied Statistics (CAS) may be done at any time. Students who are currently admitted to or enrolled in a graduate degree program that want to earn the CAS should contact the Statistics Department to enroll in the certificate program. Students who want to pursue the CAS independent of a graduate degree program must be admitted as a non-degree graduate student prior to registering for the certificate program.

Those seeking admission to the CAS must have a minimum GPA of 2.75, have graduated from and accredited institution with a minimum of a Baccalaureate degree and successfully completed College Algebra. Single and Multi-variable Calculus are recommended.

The GRE General Test is not required for admission.

To obtain a Master of Science in Statistics, the student must complete the course and comprehensive examination requirements.  The student must maintain a minimum GPA of 3.0 and earn a grade of C- or better in all courses counting toward the degree.

Major Learning Goals

statistics

Graduate courses in statistics, and sequences of statistics courses leading to a Master of Science in Statistics or a Certificate in Applied Statistics, provide a foundation of statistical literacy, statistical reasoning, and statistical thinking.  Our aim is for all of our students to be challenged and encouraged in their statistical course work.  In particular, we enable our students to

  • Appreciate the inherent variation and uncertainty of information, and understand that statistics can be a resource for improved decision making;
  • Develop critical thinking skills for application of statistics;
  • Effectively communicate the results of statistical analysis;
  • Become responsible and competent practitioners of statistics in order to attain personal goals, either in a profession or in further educational experiences.
