A Proposed New Framework for Evaluation in California:The Sampling Roadmap

摘要

The California Evaluation Framework Study (2004) was undertaken to develop a newstatewide framework for the evaluation of California energy efficiency programs. This paperfocuses on the uncertainty and sampling segments of the project. The uncertainty chapteraddresses three related topics: 1) statistical precision and bias, 2) integrating information frommultiple evaluation studies, and 3) allocating evaluation resources among planned evaluationstudies. The sampling chapter also has three main parts: 1) An overview of familiar techniquesin simple random sampling, 2) a thorough discussion of stratified ratio estimation, and 3) asampling roadmap that describes the chronological steps of a typical project. In addition, anexample was developed illustrating the application of the roadmap to an actual study. This paperprovides a concise overview of this material, highlighting some of its less familiar concepts andcontrasting the new approach to the sampling approach given in the CADMAC protocols.
