Deshpande, C. G., & Patwardhan, V. (2006, September 4). Raven Standard Progressive Matrices norms for Indian tribal areas. WebPsychEmpiricist. Retrieved September 4, 2006, from http://wpe.info/papers_table.html
Data for the Raven Standard Progressive Matrices were collected from representative samples of school attendees in nine tribal areas in India. Altogether, 6199 young people aged 8 to 21 were tested. The norms were considerably lower than both the Indian urban norms collected some years ago and those for the UK. Nevertheless, as usual, the most striking finding is the huge variance in ability within the groups: Poor educational and economic backgrounds do not have the extreme debilitating effect that many would have expected.
