A variety of techniques may be used to select a sample1 from a larger group. In appraisal, sampling may be used to select a representative portion of records for preservation from a large series that will not be preserved in its entirety. In litigation, a large records series may be sampled to determine if that series is likely to contain relevant materials. - Sampling2 determines the quality of the digital recording; the higher the frequency of the sampling rate and the greater the range of values that can be captured, the closer the digital version approximates the original performance being recorded.

(Sedona Principles 2003, p. 43) Sampling1 usually (but not always) refers to the process of statistically testing a database for the likelihood of relevant information. It can be a useful technique in addressing a number of issues relating to litigation, including decisions what repositories of data are appropriate to search in a particular litigation, and determinations of the validity and effectiveness of searches or other data extraction procedures. Sampling can be useful in providing information to the court about the relative cost burden versus benefit of requiring a party to review certain electronic records.
