WLS Codebooks
Note: Codebooks contain frequency data from the private data release. For some variables, these differ from the frequencies in the public release. Variables that differ between the public and private versions include "(not available on public release)" as part of the variable description, or a note indicating the difference between the public and private versions.
Graduate IQ
The recommended IQ measures are gwiiq_bm for graduates and swiiq_t for siblings. These measures include imputed junior year Henmon-Nelson scores. The imputations were based on scores from other grades, the Wisconsin Centile Rank, and the IOWA test. Imputed cases can be identified using the variable gflag_bm. The end of the variable name represents whether it is the preferred measures (bm), from junior year (j) or from freshman year (f) There were a variety of errors in IQ variables used prior to February 1998. These variables - IQ IQSCOR IQERR IQHNQ IQHNSCRQ IQJCR IQJSCOR IQFCR IQFSCOR IQJRS IQFRS - have been moved to the archives and are not recommended to be used unless replicating previous studies. gwiiq_* IQ score mapped from raw Henmon-Nelson test score ghnrs_* Raw Henmon-Nelson test score ghncr_* Centile rank based on National test takers for Henmon-Nelson score gwicr_* Centile rank based on Wisconsin test takers for Henmon-Nelson score gflag_* Source of Henmon-Nelson raw score gagecm_j Age in months when junior year Henmon-Nelson test was taken gagecm_f Age in months when freshman year Henmon-Nelson test was taken gtdate_f Date when graduate took freshman year Henmon-Nelson test.
