PISA Data Analysis Manual: SAS, Second Edition

The OECD Programme for International Student Assessment (PISA) surveys collected data on students’ performance in reading, mathematics and science, as well as contextual information on students’ background, home characteristics and school factors which could influence performance. This publication includes detailed information on how to analyse the PISA data, enabling researchers to both reproduce the initial results and to undertake further analyses. In addition to the inclusion of the necessary techniques, the manual also includes a detailed account of the PISA 2006 database. It also includes worked examples providing full syntax in SAS®.

Hide / Show Abstract

The PISA initial and thematic reports present results for each country and two additional aggregated estimates: the OECD total and the OECD average.

The OECD total considers all the OECD countries as a single entity, to which each country contributes proportionally to the number of 15-year-olds enrolled in its schools. To compute an OECD total estimate, data have to be weighted by the student final weight, i.e. W_FSTUWT.
