We explore non-probability sample types and explain how and why you might want to consider these for your next project.
an extremely low response rate may have no greater chance of being representative than, for example, a carefully constructed quota sample. Not all research requires high degrees of accuracy, and for exploratory research, in particular, a non-probability sample may be a perfectly appropriate strategy...
