Explain What It Means to Have a Nonrepresentative Sample

Essay

Explain what it means to have a nonrepresentative sample. Describe the situations where a pool of such participants risks dramatically limiting the extent to which results can be generalized to the rest of the population, and when using such participants is unlikely to influence results much, if at all. Provide an example study (i.e., list of 1 IV and 1 DV) that would be vulnerable to nonrepresentative-participant bias, as well as an example study that would not be vulnerable to this bias, and be sure to explain why and how those examples demonstrate what you claim that they are demonstrating.
