design factor
Definition:
The ratio of the SAMPLING ERROR of a complex sample to a simple sample. The complicated calculations required to estimate the sampling error in a complex sample are often calculated for one or two QUESTIONS in a SURVEY, and the design factor thus derived applied to estimate roughly the sampling error in other questions, or other surveys. A typical value of the factor is two.
