A sample collected concurrently, i.e. in the course of the same sample survey under comparable conditions, with a first sample. It acts in much the same way as a replication except that in some cases the only thing which can be replicated is the act of taking a second independent sample.

For example, a second independent sample in a survey will afford additional information on the sampling error but nothing has been replicated in the sense of a repeated experiment beyond the act of selecting a duplicate sample. The act of taking several such samples may be called replicated sampling.
