Analysis of Longitudinal Study of American Youth (LSAY) Data

This workshop will introduce participants to the nature and structure of the Longitudinal Study of American Youth (LSAY) data set and to the procedures needed to analyze it.

The Longitudinal Study of American Youth (LSAY) has followed a national probability sample of 7th and 10th grade public school students for the last 25 years and is the largest and most comprehensive data set available to examine the factors that contribute to student and young adult interest in and understanding of science and technology. The LSAY is distinctive in its measurement of home, school, peer, and community variables over more than two decades, making it ideal for analyses that seek to understand the interaction between and among these factors.

The course will:

Introduce the structure and logic of the LSAY data set and its naming conventions
Describe the measures of achievement in science and mathematics and review the psychometric basis for these scales
Describe the coding of open-ended items in the LSAY longitudinal record
Discuss geographic and related codes included in the data set
Discuss measurement error inherent in repeated measures and strategies for dealing with this error
Provide a general understanding of prior work using the LSAY data set
