A Problem in the Aggregation of Student Data to the Level of School. Working Draft.
Keesling, J. Ward
In many circumstances it is appropriate to use the school as the unit of analysis. The variables measured on students must be aggregated to form a mean for each school. However, the means derived from the students sampled in a school will tend to fluctuate around the true mean for the school in a way determined by the within-school correlations among student variables rather than by the between-school correlations. A model is presented which circumvents this problem by obtaining replicate measures for each variable. The model permits estimation of the true between-schools covariance matrix and measurement error variances. An example employing real data is presented. (Author)
