Abstract: The goal of this paper is to show how the statistical techniques can help to understand the news described in the media which, quite often, are misleading and, also, to test the reliability of the general opinions of the people. To this end, I have chosen to analyze the results of Spain in the PISA 2012 report as well as the performance of the Spanish sportsmen and sportswomen in the last Olympic Games. In particular, I will compare the results of Spain in both cases and I will also analyze how the wealth of the countries influence their results.
