CHANGE NOTICE #29 - data version 12.22 - February 2008

This change notice documents changes made to the WLS data between December 19,2007 and February 14, 2008.

Newly Added Variables

Addition of Summary Score with Means Imputed for Missing Components.

Prior to this release, missing values included as part of a summary score were treated as 0. Now summary scores include a second paired variable in which missing components receive the mean of the valid responses prior to summation. This new variable is only constructed if at least half of the components receive a valid response. Else the new summary measure is set to missing. The new summary variables end in the letter i. The first seven characters of the new variable are identical to the corresponding summary score available in previous releases. The older version of the summary score is retained in the data files.
