Download dataset used for SRCD Monograph analysis

Download the dataset used in TEDS analyses of learning abilities (reading, mathematics and science) and general cognitive ability at 7, 9 and 10 years as reported in:

Yulia Kovas, Claire M. A. Haworth, Philip S. Dale and Robert Plomin:
The Genetic and Environmental Origins of Learning Abilities and Disabilities in the Early School Years.
Published by Monographs of the Society for Research in Child Development.

The dataset includes measures both in standardized form (following adjustment for sex and age at the time of assessment as in our genetic analyses) and in unstandardized form (not adjusted for sex and age). Only data described in the Monograph are included in the dataset and these data are only available at the level at which they are analyzed in the Monograph. For example, in the Monograph we analyze data at the level of scales rather than individual items. Chapter 2 of the Monograph describes the measures and presents results of basic descriptive and inferential analyses.
