Sample Design and Evaluation

Sample design plays an important role in a variety of analyses, and Christensen Associates knows how to get results that are representative of the relevant population. We have extensive experience in designing samples and evaluating sample designs in a variety of contexts, including customer surveys, field reviews, site surveys, energy utility load research samples, and program evaluations.

We carefully study the population of interest to determine the most efficient sample design to meet the desired level of precision, accounting for the client’s resource constraints as needed. Where necessary, we stratify the sample to improve the efficiency and representativeness of the sample design.

Christensen Associates has applied the same methods to evaluate existing sample designs. For example, an electric utility may want to evaluate whether its load research sample requires changes in order to continue to be representative of its customers.

"This is an excellent piece of work. I don’t think the Board could have gotten a better job from Christensen…It is very easy to follow what Christensen Associates has done; people who want to replicate what [Christensen Associates has] done and check it – everything is laid out there, including all the econometric methodologies, and how things are done and results. It’s just a first-class piece of work."
