An Evaluation of Woodruffs Technique for Variance Estimation in Educational SurveysUniversity of California, Berkeley
An empirical sampling approach was used to assess the accuracy of a Taylor approximation for the estimation of sampling errors in the statistics involved in estimating a path model based on medium-sized samples gathered using five sample designs commonly used in educational research. The technique was found to give a reasonable approximation for the simplest of the designs but to deteriorate as clustering, stratification, and weighting became more pronounced.
