The paper presents the use of repeated measures analysis of variance (RM-ANOVA) in biomedical studies. Special attention is given to conceptualization of research questions, data computerization and data presentation as well as to assumptions for this method. We also discuss recommendations for presenting results of RM-ANOVA in scientific reports. For better understanding of the method we present practical example using the data on repeatedly measured blood glucose levels in patients with PCOS and healthy women from different ethnic groups after oral glucose tolerance test. Practical implementation of RM-ANOVA in R and SPSS software is also given with syntax and graphs.
