SORT (Statistics and Operations Research Transactions) —formerly Qüestiió— is an international journal launched in 2003. It is published twice-yearly, in English, by the Statistical Institute of Catalonia (Idescat). The journal is co-edited by the Universitat Politècnica de Catalunya, Universitat de Barcelona, Universitat Autonòma de Barcelona and Universitat de Girona, with the co-operation of the Spanish Section of the International Biometric Society and the Catalan Statistical Society. SORT promotes the publication of original articles of a methodological or applied nature or motivated by an applied problem in statistics, operations research, official statistics or biometrics as well as book reviews. We encourage authors to include an example of a real data set in their manuscripts.
SORT is indexed in the "Science Citation Index Expanded" (Thomson Scientific) and described in the "Encyclopedia of Statistical Sciences". The journal is also referenced in the "Current Index to Statistics", the "Índice Español de Ciencia y Tecnología", "Statistical Methods and Abstracts", MathSci of the American Mathematical Society ("Current Mathematical Publications and Mathematical Reviews") and “Scopus”. In 2011, SORT has also obtained the certificate of excellence given by Fundación Española para la Ciencia y la Tecnología which guarantees publishing and scientific quality. SORT represents the third series of the Quaderns d'Estadística i Investigació Operativa (Qüestiió), published by Idescat between 1992 and 2002, which in turn followed from the first series "Quaderns d'Estadística, Sistemas, Informàtica i Investigació Operativa" (1977–1992). The three series of Qüestiió have their origin in the "Cuadernos de Estadística Aplicada e Investigación Operativa", published by the Universitat Politècnica de Catalunya until 1977.

SORT was indexed in the "Science Citation Index Expanded" (Thomson Scientific) beggining by volume 31 (1) 2007. In June 2012 the Impact Factor 2011 of SORT tracked by Thomson Reuters (ISI) for three years has been released: 0,429.
The Impact Factor is established by dividing the number of times articles published in 2009 and 2010 were cited in 2011, based on a search of the Science Citation Index Database, by the number of articles published in the previous two years (2009 and 2010).
