Again, this is another example of the dangers of raw, unadjusted non-probability samples and is reminiscent of the Literary Digest fiasco.
Figure 3.6: Probability sampling in practice and non-probability sampling are both large, heterogeneous categories.
One possible reason for these differences is that non-probability samples have improved over time.
For example, by using non-probability methods the Cooperative Congressional Election Study(CCES) is able to have roughly
The second reason why researchers should reconsider non-probability sampling is because probability sampling in practice are become increasingly difficult.
In general, there is a cost-error trade-off with non-probability sampling being lower cost but higher error.
This framework enables us to understand new approaches to representation- in particular, non-probability samples(section 3.4)-
But, it does mean that when comparing non-probability samples to probability samples in practice,
probability samples and non-probability samples are not as different as many researchers believe.
In conclusion, social scientists and statisticians are incredibly skeptical of inferences from these non-probability samples, in part because they are associated with some embarrassing failures of survey research such as the Literary Digest poll.
When using post-stratification to make estimates from their non-probability sample, Wang
As I said earlier, non-probability samples are viewed with great skepticism by social scientists,
it is still among the reason that some researchers are skeptical about estimates from non-probability samples. Source.
For a more pessimistic view of non-probability sampling methods see the the AAPOR Task Force on Non-probability Sampling(Baker et al. 2013),
currently it is likely the case that most estimates from probability samples are more trustworthy than estimates from non-probability samples.
probability samples and non-probability samples are not as different as many researchers believe.
There are a variety of styles of non-probability sampling methods, but the one thing that they have in
Non-probability sampling methods have a terrible reputation among social researchers
One thing that is clear, however, is that if you are forced to work with non-probability samples or nonrepresentative big data sources(think back to Chapter 2),
These newer methods are different enough from the methods that caused problems in the past that I think it makes sense to think of them as“non-probability sampling 2.0.” The second reason why researchers should reconsider non-probability sampling is because probability sampling in practice are become increasingly difficult.
