Creative Component
The Masters degree in Quantitative Methods requires the student to analyze 2-3 data sets from conceptually distinct social and behavioral areas using two or more methodologies and to write a brief report of the findings. Each report will entail signing up for 1 credit of Psych 599 (Creative Component) for a total of 2-3 credits.  The analyses and reports are designed to provide students with an opportunity to develop their quantitative skills by playing the major role in analyzing social and behavioral research data. The specific projects will be determined by the faculty mentor, guided by the student’s and the mentor’s interests, and approved by the student’s POS committee.

Ph.D. CO-MAJOR IN STATISICS AND PSYCHOLOGY

Students must formally apply for admission to the Ph.D. programs in Statistics and Psychology. The student will have a major professor in Statistics and a major professor in Psychology. The POS committee will consist of at least two faculty members from each department.

MORE INFORMATION ABOUT QUANTITATIVE PSYCHOLOGY
In 2006, the American Psychological Association authorized a special task force to study the problem of a growing demand and a decreasing number of quantitative psychologists.
