PhD in Statistics

The STEM-designated PhD in Statistics program provides advanced training in topics including probability, linear models, time series analysis, Bayesian statistics, inference, reliability, statistics in law and regulatory policy and much more.

Nearly all GW statistics PhD graduates have secured job placements in the statistics or data science industry, with employers including Amazon, Facebook and Capital One. During the program, PhD students work closely with faculty on original research in their area of interest. 

The degree provides training in theory and applications and is suitable for both full-time and part-time students. Most graduate courses are offered in the early evening to accommodate student schedules. 

Application Deadline: January 15, 2022

 

    Application Requirements

    Prospective PhD students typically have earned a master’s degree in statistics or a related discipline. Students need a strong background in mathematics, including courses in advanced calculus, linear algebra and mathematical statistics.

    "GW encouraged me to tap into expertise from within as well as outside the university while researching my dissertation topic. I learned about the value of collaboration throughout my doctoral studies. Collaboration is so important in science, and it’s been instrumental in our success at Emmes."

    Advising

    Students in their first semester of the PhD in Statistics program must meet with the program director prior to signing up for classes. Students should continue to seek advice from the advisor throughout the program, particularly when determining whether any previous coursework can be applied toward their degree.

     

    General Examinations

    The general examination consists of two parts: a written qualifying examination and an examination to determine the student's readiness to carry out the proposed dissertation research.

     

    Qualifying Examination

    Each PhD candidate is required to take and pass the PhD qualifying exam. The exam is given at the beginning of the fall semester each year. No more than two attempts are permitted. 

    It consists of two papers:

    • Inference: STAT 6202 and 8263
    • Probability: STAT 6201 and 8257

     

     

    Readiness Examination

    After passing the qualifying examination, the candidate should select a dissertation advisor. In consultation with the advisor, the candidate should pass a readiness examination, usually consisting of a research proposal and an oral examination. A committee of at least two professors should administer the readiness examination.

     

    Dissertation

    Students are required to complete a written dissertation that should be defended before an examination committee of at least four examiners. The dissertation should contain original scholarly research and must comply with all other GW rules and regulations. For more guidance on dissertation process, review the CCAS PhD Student Handbook. For formatting and submission guidelines, visit the Electronic Theses and Dissertations Submission website.

    Course Requirements 

    The program requires 72 credit hours, of which at least 48 must be from coursework and at least 12 must be from dissertation research. Up to 24 credit hours may be transferred from a prior master’s degree (contrary to general GW doctoral program requirements, which allow up to 30 transfer credit hours).

    Prerequisite: a master’s degree in statistics or a related discipline. The main requirement is a strong background in mathematics, including courses in advanced calculus, linear algebra, probability and mathematical statistics. Some deficiencies may be made up concurrently during the student’s first year. In some instances, a student may enter the PhD program with a bachelor’s degree.

    The following requirements must be fulfilled:
