The subjects of the study are Olympic Games of 1992, 1996 and 200. By use of quantile regression to formulate the econometric model, some variables of the participating countries are taken as independent variables. Variables such as the size of the participating countries, population, economic capacity, construction capacity, globalization and mobility are the examples.
