About Us

Sara Gottlieb-Cohen, PhD

StatLab Manager

Sara is the Manager of Statistical Support Services at Yale University and holds a PhD in cognitive psychology from the University of California, Berkeley. Her research interests fall at the intersection of psychology and philosophy and her graduate work investigated how people think about science and the limits of scientific knowledge. She holds expertise in experimental design and analysis, and has taught data analysis and statistics at the undergraduate and graduate level. She looks forward to helping patrons with a range of statistical and programming needs.

Software and computing: R, SPSS, Qualtrics, Excel, Mechanical Turk

Methodological topics: Hypothesis testing of all sorts (e.g., ANOVA, t-test, chi square), regression analysis, mixed-effects/hierarchical models, power analysis, experimental design, survey design, data wrangling, data visualization 

Spoken languages: English

Our Consultant Team

Our consultation team consists of graduate students from across Yale University.

Each consultant is able to discuss basic statistical and data analytic techniques. However, when you are looking for help with a specific program or topic, we encourage you to find the right consultant and check our schedule before you visit.

What expertise are you looking for?

Our consultants have a working knowledge of many techniques and tools. However, they also have expertise on specific tools and methodologies, do their own research in particular academic fields, and provide consultation services at different locations across campus.

Because of this, we suggest you find the best match for your particular needs before coming to one of our walk-in sessions. 

Please email statlab@yale.edu with questions about meeting with a specific consultant. Direct emails to consultants will not get a prompt reponse.
