Advocates of basic research argue that the more basic the principle being studied, the less it matters who participates in the study in terms of sample representativeness.
In the field of qualitative research, representativeness refers to the need for a sample to be collected using methods reliant upon probability. A sample is also said to be representative, when the small sample, after being tested, exhibits traits consistent with or similar to the larger group.
