PSYCH 3500: Statistics and Research Design

An overview of statistical analysis and research design as they pertain to psychological science, broadly construed.

General information about the course

Starting in Fall 2012, this course will have 3-credit and a 4-credit options.  Both options cover the same course material at the same depth of analysis.  However, the 4-credit option also includes training in the use of statistical software  (specifically, R).  All course materials will be available to all students irrespective of the option they select, but software-based assignments will only be graded for students taking the fourth credit.  If you are planning on doing honors research, then taking the fourth credit is definitely advisable. 

·         Syllabus from Fall 2011 (pdf)

·         Links to download the R environment and the supplementary enhanced environment RStudio.  You should install the basic R environment before installing RStudio.  Both are free (as in both beer and freedom), cross-platform (Macintosh, Windows, Linux), and open-source. 

Information about the statistics requirement for the Psychology major

Psychology 3500, Statistics and Research Design, is the standard statistical analysis course for the Psychology major. Psychology majors should plan on taking it. However, if this is not possible, other statistics courses taught at Cornell can also satisfy the major requirement. The final decision on whether a given course is acceptable rests with your major adviser. That said, you generally can expect the following policy:

The following courses are acceptable:

·         PSYCH 3500

·         PAM 2100 (Introductory statistics)

·         STSCI 2200/BTRY 3010 (Biological statistics I)

The following are sometimes acceptable:

·         AEM 2100 (Introductory statistics) -- probably OK; still under review

·         ECON 3190 (Intro to stats and probability) -- if and only if you are a Psych/Econ double major

The following generally do not meet the requirements of the psychology major

·         MATH 1710

·         ILRST 2100 / STSCI 2100   -- the full-year version of this course may be OK; check with the Psych 3500 instructor

Contact me regarding any other statistics courses, and please send along a PDF of the course syllabus and (if you have already taken it) tell me your grade in the course. You can also challenge the statistics requirement by taking a comprehensive exam covering the subject matter.

This is not a judgment of the quality of other courses; rather, it is an issue of which statistical principles are most relevant for particular major fields, such that they must be covered in some depth and in the appropriate context for their likely use within the field. Some introductory statistics courses, for example, cover regression analyses in greater depth at the expense of means testing (e.g., two-factor ANOVA, repeated-measures ANOVA, post hoc tests) and nonparametric tests of significance (chi-square, Kruskal-Wallis' H); these analyses are an essential component of introductory statistics for psychological science.
