ARG economists and statisticians have extensive experience designing sampling methodologies and survey questions, as well as determining the correct sample size and stratification methodology as appropriate.

Representative Engagements

• For a major insurance company, ARG statisticians designed a statistically valid sampling methodology and survey questionnaire to poll brokers and quantify the extent to which certain underwriting guidelines were followed when representatives sold automobile insurance policies.
• For an international bank facing a proposed wage and hour class action law suit, an ARG statistician filed an expert affidavit describing the necessary sample sizes and stratification to achieve alternative margin of errors. Our cross-examination testimony successfully rebutted plaintiffs’ statistician’s opinions. Class certification was denied.
• For a major healthcare institution in a dispute with insurers regarding reimbursements, ARG statisticians designed a sampling methodology and oversaw an analysis of medical services records. The insurers accepted our sample design and findings.
• For a packaging manufacturer in a patent infringement matter, ARG statistical experts designed a sampling methodology to select a random sample of various products. Because the products were destroyed as part of the inspection process (in determining the effectiveness of the design-around procedure), the sample was designed to be as small as statistically permissible to generate reliable inferences.
