临床医生依靠言语、语言和听力科学研究的准确性来改善对沟通障碍患者的评估和治疗。虽然这项工作对临床护理的巨大进步做出了贡献，但常见的统计误解仍然存在，值得在该领域进行更仔细的检查。应用和解释传统统计方法与人类行为数据的挑战导致了在其他相关科学领域（包括心理学和医学）的复制和再现困难。研究的重要性，在我们的研究领域，为推进科学和临床护理，为我们的病人意味着统计方法的选择可以有深远的，现实世界的implication.MethodThe的目标，这篇文章是提供一个概述的基本统计概念和方法，用于语音，语言和听力sciences.ResultsWe重新介绍基本的统计术语，如thepvalue和效应大小，以及推荐的程序模型选择和多重comparison.ConclusionsResearch在讲话，语言和听力科学可以有一个深刻的积极影响个人的生活与沟通障碍，但在我们的领域的科学发现的有效性增强时，数据进行分析，使用健全的统计方法。对基本统计原则的误解或曲解可能会损害公众对研究结果的信任。提供了有助于最大限度地减少统计推断错误可能性的实践建议。补充材料https：doi.org/10.23641/asha.7849223
PurposeClinicians depend on the accuracy of research in the speech, language, and hearing sciences to improve assessment and treatment of patients with communication disorders. Although this work has contributed to great advances in clinical care, common statistical misconceptions remain, which deserve closer inspection in the field. Challenges in applying and interpreting traditional statistical methods with behavioral data from humans have led to difficulties with replication and reproducibility in other allied scientific fields, including psychology and medicine. The importance of research in our fields of study for advancing science and clinical care for our patients means that the choices of statistical methods can have far-reaching, real-world implications.MethodThe goal of this article is to provide an overview of fundamental statistical concepts and methods that are used in the speech, language, and hearing sciences.ResultsWe reintroduce basic statistical terms such as thepvalue and effect size, as well as recommended procedures for model selection and multiple comparisons.ConclusionsResearch in the speech, language, and hearing sciences can have a profound positive impact on the lives of individuals with communication disorders, but the validity of scientific findings in our fields is enhanced when data are analyzed using sound statistical methods. Misunderstanding or misinterpretation of basic statistical principles may erode public trust in research findings. Recommendations for practices that can help minimize the likelihood of errors in statistical inference are provided.Supplemental Materialhttps://doi.org/10.23641/asha.7849223
