Biostatistics Core

The Biostatistics Core at ACRI provides comprehensive assistance with study design, data analysis, and statistical results interpretation.  The core is staffed by two doctoral level statisticians and two master’s level statisticians who are available to support researchers of Arkansas Children’s with statistical applications related to basic science, clinical, health outcomes, epidemiologic, and behavioral research.  Our statisticians have knowledge and expertise in SAS, open-source R, and SPSS software packages.

Consulting for grant proposal preparation is free. Costs associated with statistical support needed during the project period should be included in the grant application budget.

  • Intramural Applications:  Proposal budgets should include a single charge for statistical support that is based on the approximate total hours of engagement.
  • Extramural Applications:  Proposal budgets should include salary support at the level of effort required to complete the work.  Effort determinations will be based on the extent and volume of work (scope of the project).  Work is defined as study design, drafting of data analysis plan, data analysis/interpretation, and reporting.
