Experimental Design Series
WVCTSI's Biostatistics, Epidemiology and Research Design has developed a special interactive series on experimental design. Attendees will participate in case studies, group discussions and practical exercises on a wide variety of experimental design topics. Participants are also encouraged to bring their own research questions or study designs for discussion. Sessions in this series will take place on listed Thursdays beginning at 4 p.m. A full list of session topics and dates can be found below.
Presented by:
