duplication  

Definition

  • Duplication refers to the prevalence of an element more than one time on a sampling frame, assuming that the element appears only once in the target population but appears more than once in the sampling frame. As straightforward as this problem and its solution may appear to be, its detection and correction can be complicated, time-consuming, and/or costly.
