This is a mini-book derived from the Pediatric Emergency Medicine Question Review Books 2009, 2013, and 2017. In recognition that some in our specialty may want all of the statistics and research methodology review from our books, and since these questions and answer sets are likely to be helpful for other specialties, we have extracted and combined all related question and answer sets from the 2009, 2013, and 2017 editions of the Pediatric Emergency Medicine Question Review Book. The contents are identical to previously published titles: Pediatric Emergency Medicine Question Review Book: Just the Statistics 2009, 2013, 2017 and Statistics and Research Methodology Review for Medical Board Examinations Pediatric Emergency Medicine Question Review Books 2009, 2013, 2017. Each chapter has been written by board-certified PEM attending physicians, and all chapters have been reviewed by the Editors. In addition, for this mini-book, all question and answer sets have been re-reviewed, edited, and updated in 2017, including a thorough review by a PhD statistician (Peter Chi).
