COVID-19 Notice: Groups involved with study design, conduct, statistical analysis, and reporting at GWU and Children’s National Hospital are coordinating to provide priority response to COVID-19 studies. For more information, click here.

The CTSI-CN's Biostatistics, Epidemiology, and Research Design (BERD) module also provides support related to Data Analysis and Proposal Development and Study Design.

The team is trained on a variety of statistical techniques from basic hypothesis testing to advanced modeling techniques. We also provide power and sample size calculations and will write the methods sections for your proposal submission or manuscripts. Often, presentation of results are built around the specification of the journal chosen for publication.
