BACKGROUND: Residents' ability to interpret statistics is important for scholarly pursuits and understanding evidence-based medicine. Yet there is limited research assessing residents' statistical literacy and their training in statistics. METHODS: In 2011 we surveyed US obstetrics-gynecology residents participating in the Council for Resident Education in Obstetrics and Gynecology In-Training Examination about their statistical literacy and statistical literacy training. RESULTS: Our response rate was 95% (4713 of 4961). About two-thirds (2980 of 4713) of the residents rated their statistical literacy training as adequate. Female respondents were more likely to rate their statistical literacy training poorly, with 25% (897 of 3575) indicating inadequate literacy compared with 17% (141 of 806) of the male respondents (P < .001). Respondents performed poorly on 2 statistical literacy questions, with only 26% (1222 of 4713) correctly answering a positive predictive value question and 42% (1989 of 4173) correctly defining a P value. A total of 51% (2391 of 4713) of respondents reported receiving statistical literacy training through a journal club, 29% (1359 of 4713) said they had informal training, 15% (711 of 4713) said that they had statistical literacy training as part of a course, and 11% (527 of 4713) said that they had no training. CONCLUSIONS: The findings suggest that statistical literacy training for residents could still be improved. A total of 37% (1743 of 4713) of obstetrics-gynecology residents have received no formal statistical literacy training in residency. Fewer residents answered the 2 statistical literacy questions correctly compared with previous studies.
