Welcome to McArdle GC-3 Center!


The aim of the John J. McArdle Graduate Consultation and Computer Center (GC3) is to provide free statistical consultation to progressive masters students, doctoral students and faculty in the USC Psychology Department. The center provides support for students working on research projects, including but not limited to: poster presentations, symposia, journal articles, theses, and dissertations. The center is equipped with computers, as well as a variety of statistical programs for students and faculty to use with or without the assistance of the GC3 consultants. The center also provides workspace for those to bring their own computers and work on projects, individually or as small teams.
