Program Learning Outcomes
Upon completion of the doctoral degree, students in the Data Science program are expected to be able to:

• Demonstrate competency in the core concepts and techniques of data science, which come from both computer science and statistics.
  
• Demonstrate the ability to use or develop appropriate techniques to analyze structured, unstructured, or dynamic datasets.
  
• Demonstrate an understanding of the principles that underlie analytical methods, to articulate the strengths and limitations of analytical methods, and to defend choices to use some methods over others.
• Demonstrate the ability communicate effectively to technical and non-technical audiences orally, in writing, and with effective visualization.
• Demonstrate the ability to identify and respond to ethical concerns with the provenance and use of data.
  
• Demonstrate the ability to develop new techniques for the analysis of complex datasets or real-time modeling and decision-making, or extend existing techniques to novel and challenging datasets.
  
• Demonstrate the ability to organize data using tools appropriate to the problem, code new techniques in the appropriate computer language, optimize for performance and scalability, and distribute new tools to the data science community in a usable form.
  

Prerequisite to Graduate Work
Prerequisite coursework includes the areas listed below. When applying, if previous courses and/or professional experience do not clearly indicate background in these areas, please clearly specify how these prerequisites have been satisfied in your personal statement.

• Differential, integral, and multivariate calculus (BGSU equivalent of Math 1310, 2320, and 2330/2350)
• Linear Algebra (BGSU equivalent of Math 3320)
• Senior-level Introduction to Probability (BGSU equivalent of Math 4410)
• Senior-level Statistics (BGSU equivalent of Math 4420)
• Programming skills in high level languages such as C, C++, Java, Python (BGSU equivalent of CS 2010 and 2020)
• Data structures (BGSU equivalent of CS 3350)
• Algorithms (BGSU equivalent of CS 4120/5120)

Admission Procedure
Applicants must complete the admission process required by the Graduate College that includes submission of the complete online application, all previous college and university official transcripts (a minimum GPA of 3.0 required), GRE General Test or GMAT scores, statement of purpose, resume, three letters of recommendation from faculty or professionals in the field, and, for certain international students, TOEFL or IELTS scores. Applicants should refer to the Graduate Admissions web site for a complete list of admission procedures. 

Admitted  students who do not have an earned master’s degree in data science, statistics, applied statistics, computer science, mathematics, or a closely related field, will be enrolled in the 90 credit pathway and will first complete the 30 credit Data Science Master’s program before entering the 60 credit post-master PhD program. Students with an earned master’s degree in data science, statistics, applied statistics, computer science, mathematics, or a related field should have the course background that makes it possible to immediately take PhD-level courses in computer science or statistics.  Others who have been determined by the Program Committee to need additional prerequisite coursework may be admitted to the 60 credit pathway with additional credit requirements.

   3. (MS-level) CS 5200-5620

Preliminary Examination: 
A student must pass the Qualifying Examination to qualify to take the Preliminary Examination. The Preliminary Examination includes a written and an oral component. This is a research-oriented examination intended to help prepare students to begin their dissertation research. The Preliminary Examination Committee must have representation from at least two of the three departments participating in the program.

Dissertation:  
A doctoral candidate must enroll in at least 16 credit hours of dissertation work (DATA 7990), up to a maximum of 30 credit hours.
