An Econometric Model for Estimating IQ Scores and Environmental Influences on the Pattern of IQ Scores Over Time.
Kadane, Joseph B.; And Others
This paper offers a preliminary analysis of the effects of a semi-segregated school system on the IQ's of its students. The basic data consist of IQ scores for fourth, sixth, and eighth grades and associated environmental data obtained from their school records. A statistical model is developed to analyze longitudinal data when both process error and measurement error must be accounted for. IQ tests are used in this paper as convenient measures of a certain kind of performance thought to be important for success in schools and certain kinds of jobs. Most of the environmental variables included in the model can be construed to measure the nature or degree of contact with mainstream culture. The data were collected in the summer of 1971 from the cumulative school records of all students who had just finished the ninth grade in the Pittsburgh public school system. The time period examined is nine years between 1962 and 1970, during which time a proportion of the group passed from kindergarten to eighth grade in the Pittsburgh system. IQ tests were administered during this period to children in kindergarten, fourth, sixth, and eighth grades. The tests administered were the Detroit (kindergarten), Kuhlmann-Anderson (fourth grade), Otis Beta FM (sixth grade), and Otis Lennon (eighth grade). (Author/JM)
