Grad Spouse IQ

OVERVIEW:

Spouse IQ data were collected for all spouses where we had a valid high school
name, maiden name, and either DOB or year graduated.

Information about Spouse IQ was collected in the following way:

-In 2003-2004 we began speaking to graduate and sibling spouses.  While
interviewing spouses we ascertained their maiden name, whether or not they
attended high school in Wisconsin, if so what high school they attended, and
finally their date of birth.

-With the above information collected we were able to use spouses date of birth
and high school information to calculate estimations of the year in which
spouses were in particular grade levels and in what school.  We then used these
estimations combined with their maiden name to search through the Wisconsin
Cooperative Testing Program books for Spouses Henmon-Nelson scores (books with
scores exist for WI schools from 1930-1980).

-Each case was checked three times; 1.)The first check was done quickly on the
estimated year. 2.) For cases that did not yield a score on the first check we
looked at plus and minus three years from the estimated year.  In addition, if
the reported high school was in a big city we checked all other high schools in
that city. 3.) After the first two checks, if a case did not have 2 scores we
checked all high school years without a score in the same manner as check 2.

-Finally, once Hemnon-Nelson scores were located for spouses we followed an
already established formula (see Cor652, Memo124) to convert raw Henmon-Nelson
scores for grades 9-12 taken in any year into the metric of  Wisconsin IQ
scores jor Juniors in 1957.  In this way (for example), a score from a spouse
who took the test as a 9th grader in 1938 could be compared to a graduate who
took the test as a Junior in 1956.


BRIEF VARIABLE DESCRIPTIONS: 

NOTE:  "Best measure" (bm) represents spouse's junior year score, if no junior
score exists then we used the converted senior year score, if no senior then
sophomore, if no sophomore then freshman.
