The statistical concepts discussed in this review are intended as a basis to understanding concepts that will be presented in PHYSICAL THERAPY during the coming months. The basis for hypotheses testing is probability theory. When a null hypothesis is either accepted or rejected, researchers are stating the probability that a specific treatment will be more or equally effective in a specific population under stated conditions. This ability to predict, based on appropriate application and interpretation of statistical tests, ultimately improves patient care.
本综述中讨论的统计学概念旨在作为理解未来几个月将在《物理治疗》中呈现的概念的基础。假设检验的基础是概率论。当原假设被接受或拒绝时，研究人员是在陈述特定治疗在规定条件下对特定人群更有效或同样有效的概率。基于对统计检验的适当应用和解释进行预测的这种能力最终会改善患者护理。
