Biostatistics Resource

The ACRI Biostatistics Resource provides comprehensive support in study design, sampling, data collection methods, analysis, and interpretation. Our team includes doctoral and master's level statisticians who assist researchers at Arkansas Children’s across basic science, clinical, health outcomes, epidemiologic, nursing and behavioral research. The team is proficient in common statistical software, including R and SAS. The biostatisticians are actively involved in research projects ranging from brief consultations to long-term collaborative research.
