Text

In evaluating the savings from a program, there is usually a budget constraint that creates the need for a trade-off between measurement accuracy and statistical precision. That is, within a given budget collecting more or more detailed data to give greater accuracy of measurement for individual sites may mean collecting data for fewer sites, thus decreasing the statistical precision of the results. Accordingly, for each program evaluated the sampling plan for determining the number of sites for which the analysis of savings needs to be performed must balance off the measurement and statistical considerations.
