Biostatistics Collaboration Center Lecture Series
Biostatistics in Medical Research

The Biostatistics Collaboration Center (BCC) in the Northwestern University Feinberg School of Medicine will be offering a series of 6 free introductory lectures on biostatistics in medical research.  The lectures will be non-technical and have been designed with the following objectives:

• To assist participants in interpreting statistics published in the medical literature.
• To highlight different statistical methodology for investigators considering their own research.
• To facilitate the communication between medical researchers and biostatisticians.

The lectures are FREE and open to interested members of the Northwestern community!  Click here to download flyer.  Registration is NOT required.  Seating is available on first come basis.  Lectures are 1 hour in length followed by 30 mins of Q&A.  Lecture slides will be available to view and download one week prior to each lecture.
