Psychometric Lab
Our Resources
The Psychometric Laboratory, is currently housed inside the LPRC, in the College of Education. The Lab houses state-of-the-art equipment for research and teaching activities including psychometric and statistical software, technical manuals and statistical and psychometric references. The Lab has access to various communications systems and high-speed internet connections to facilitate real time meetings.
There is a suite of computers for projects and teaching. We have access to high-speed computing clusters on campus. Our software includes typical software used in research in measurement and psychometrics (e.g., SAS, SPSS, R, LISREL, Mplus, IRT-specific software, HLM, and so forth). Researchers have access to serve space for storage of data.
