What We Offer and Who is Eligible

JHBC consults with JHSPH graduate students on research for their thesis, dissertation or other individual research projects on which the student is the lead author.

These consultations are provided through FREE walk-in clinics. NOTE: JHBC does not consult on coursework, nor do its services replace statistical oversight by the student’s academic committee or research mentor.

Consultations are available on study design, sample size and power calculations, organization of data for statistical analysis, statistical analysis approach, and assistance with implementing analyses in statistical software (STATA, SAS, R).

Time of Clinics and Sign-up

Walk-in clinics are available most Fridays from 10:30 a.m. – noon, for half-hour consultation sessions. Signing up for a consultation is in-person and starts at 10:15 a.m. on the day of the clinic in E-3141 (JHSPH) on a first-come, first-served basis. Biostatisticians available for clinics have rotating schedules, and the biostatistician providing the consultation will be matched as closely as possible to the student’s needs. Consultation is limited to in-person during clinic hours.

To provide support to the many students requesting these free consultations, JHBC limits a student’s access to clinic consultations to 6 times in 6 months. After 3 consultations, an email will be sent to the student’s advisor indicating that the student’s research may need more support than can be provided by JHBC.

How to Make Efficient Use of the Clinic

Consultation time is limited and the student should come prepared to facilitate the biostatistician’s understanding of their research project. This includes a description of the research hypotheses, the population to be sampled or included in existing source data, outcomes measured and to be analyzed, and their question of interest. If the question is related to sample size/power, clinically significant effect sizes for the primary outcome based on literature or previous pilot studies, and levels of precision or power required will be needed. These consultations also expect the student to have a basic understanding of statistics.
