HS.ability.data: Holzinger & Swineford (1939) Ability in 301 children from 2 schools

Description

This classic data set contains of intelligence-test scores from 301 children on 26 tests of cognitive ability.

The tests cover mental speed, memory, mathematical-ability, spatial, and verbal ability as listed below.

The data are also available in the MBESS package.

Details

The data are from children who differ in grade (seventh- and eighth-grade) and are nested in one of two schools (Pasteur and Grant-White). You will see it in use elsewhere, both in R (lavaan, and MBESS), and in Joreskog (1969) reporting a CFA on the Grant-White school subject subset.

Some tests are alternate or substitute forms, e.g. paperrev (a paper form board test) can substitute for paper and flagssub for the lozenges test flags.
