Statistical methods and their applications to study the large scale structures indicated by different objects, an important part of the mapping of the Universe, are addressed. From the observational data a number of statistical results that give constraints to the current models of galaxy formation are obtained. Theoretical models for the large scale structure formation in the Universe are summarized together with a number of catalogs that can be used for statistical purposes. During the study of the statistical methods for characterizing large scale structures special attention was given to the error analysis in these statistics. The angular two and three point correlation functions of the European Space Observatory (ESO)-Uppsala Catalog are estimated in angular diameter limited samples and the diameter function given by Lahar et al. is used to scale the results. The aim is to test the universality of some early results by using differently selected samples and samples formed in different regions. The morphological segragation of galaxies on large scales is analyzed together with the luminosity seggregation in the galaxy distribution. The large scale structure indicated by clusters of galaxies is then investigated using both the Abell and Zwicky catalogs. Outlook for future work is given.
