Abstract. The use of statistical methods on samples of astronomical data are discussed. We discuss the application of bootstrap to estimate the errors in measuring the two-point correlation function for galaxies and the topology of the large-scale structure. We discuss a technique to estimate the statistical significance of filamentary structures in the distribution of galaxies. Extreme value statistical theory is applied to the problem of the nature of the brightest galaxies in rich clusters.
