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.


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.

1)  All of the following:
    Stat 500 Statistical Methods
    Stat 511 Statistical Models
    Stat 579 Introduction to Statistical Computing
    Stat 542 Theory of Probability and Statistics
    Stat 543 Theory of Probability and Statistics
    Stat 601 Advanced Statistical Methods
    Stat 611 Theory and Applications of Linear Models
    Psych 501 Foundations of Behavioral Research

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. Information about the job outlook for quantitative psychologists and a listing of Ph.D. programs in quantitative psychology can be found at: http://www.apa.org/science/quant.html.
