Vanderbilt Biostatistics Shared Resource

About Biostatistics Shared Resource


The Biostatistics Shared Resource team work with Cancer Center investigators to:

  • Define objectives and endpoints
  • Analyze pilot data
  • Select an appropriate design
  • Devise a blinding and randomization scheme
  • Plan interim analyses
  • Determine the early stopping rules
  • Compute an adequate sample size with concern for the clinical as well as statistical significance
  • Estimate the time required to accrue the total patient population
  • Specify the statistical methods
  • Prepare statistical sections of the grant and protocol applications
  • Design relational database


The members of the Biostatistics Shared Resource endeavor to:

  • Provide consultative services for Cancer Center investigators in the statistical design, conduct, and analysis of studies
  • Collaborate in funded research efforts initiated by Cancer Center laboratory and clinical investigators, by providing statistical expertise in study design, power and sample size analysis; data analysis; interpretation of results; and writing of manuscripts
  • Provide relational database design, data tracking, forms, queries, and reports for investigator-initiated clinical trial databases or laboratory study databases
  • Develop and evaluate statistical methods for experimental design and data analysis
  • Work with the Cancer Center Clinical Trials Shared Resource in the development of a new research project database to maintain data quality control and ensure timely data capture
  • Train VICC members in research design and data analysis through seminars, short statistical workshops, and individual sessions on statistical methods


There is no charge-back for using the Biostatistics Shared Resource since biostatistical input is crucial to most clinical and laboratory studies; however, the Cancer Center requires that at least one of the resource staff be listed as co-investigator on related research grant applications.
