Abstract: The article examines the underlying assumptions, applications, and interpretations of Analysis of Variance (ANOVA) in rehabilitation research. ANOVA is presented as a widely used and highly versatile statistical tool for assessing the performance of two or more groups on a broad range of dependent variables. Examples from the contemporary rehabilitation literature are used to demonstrate how ANOVA can be applied and interpreted in a number of scientific contexts.
