Abstract
The observed gain in IQ scores over time has been examined and supported. Nonetheless, this phenomenon (also called Flynn effect) may depend on age groups and country types. This article provides raw data from three standardized intelligence tests, namely, Coloured Progressive Matrices (CPM), Standard Progressive Matrices (SPM), and Advanced Progressive Matrices (APM). The datasets contain mean IQ scores from APM, CPM, and SPM, and standard deviations, sample sizes, years of publication, participants' groups, types of countries, country-based samples, and gender of participants. This data was obtained from 199, 369, and 176 individual study samples for CPM, SPM, and APM, respectively, and covered a period of 65 years (1950-2014). There were 202,468 participants in total. An analysis and interpretation of results based on a cross-temporal meta-analysis for mean IQ scores from CPM, SPM, and APM over time can be found in the article "A Cross-Temporal Meta-Analysis of Raven's Progressive Matrices: Age groups and developing versus developed countries" (Wongupparaj, Kumari, Morris, 2015) [1]. These datasets can provide an extensive overview of the literature on Flynn effect across age groups, countries, and gender. In addition, they can serve as a useful starting point for further meta-analyses of IQ scores derived from CPM, SPM, and APM.
