Repeated measures, constitute the main type of data for many scientific fields and especially biometrics. For this reason, the methodology of their analysis, over the last years has been developed, leading to advanced models and tools. The research methodology mostly aims in the analysis of continuous responses, providing a very wide spectrum of theory and software. The last few decades, research has been extended into discrete responses and mostly ordinal. In this project, the main goal is to analyze data of repeated measures with an ordinal response. Our application is a study on women with breast cancer. We present the nature of the data and a descriptive analysis of them. There is also, an extended part on the way and the instrument the data were collected. Afterwards, the theoretical part of the analysis of ordinal repeated measures is presented, concluding to the basic assumptions and steps that have to be made. Finally, the analysis of the data using the statistical software SPSS follows, while discussing the use of other alternative available software is discussed.
