Second era 1960- 2000 Random digit dialing(RDD) probability sampling.
The alternative to probability sampling is non-probability sampling.
Currently, the dominant theoretical approach to representation is probability sampling.
Probability sampling methods and non-probability sampling methods.
Online panels can use either probability sampling or non-probability sampling. .
Currently, the dominant approach to sampling for social research is probability sampling.
For a more formal definition of probability sampling designs, see chapter 2 of Särndal, Swensson, and Wretman 2003.
Some people find it surprising that this is true even when there is perfectly executed probability sampling.
Of course, it would be better to do perfectly executed probability sampling, but that no longer appears to be a realistic option.
Figure 3.6: Probability sampling in practice and non-probability sampling are both large, heterogeneous categories.
The first era of survey research was characterized by area probability sampling and face-to-face interviews.
I will start by introducing probability sampling,then move to probability sampling with nonresponse, and finally, non-probability sampling.
This second era, roughly from 1960- 2000,was characterized by random digit dialing(RDD) probability sampling and telephone interviews.
Over time, the differences between probability sampling in theory and probability sampling in practice have been increasing.
In probability sampling, all members of the target population have a known, nonzero probability of being sampled, and all people who are sampled respond to the survey.
Sometimes researchers want a quick andrigid rule(e.g., always use probability sampling methods), but it is increasingly difficult to offer such a rule.
There are a variety of styles of non-probability sampling methods, but the one thing that they have in common is that they cannot easily fit in the mathematical framework of probability sampling Baker et al.
The main difference between probability andnon-probability sampling is that with probability sampling everyone in the population has a known probability of inclusion.
Thus, it is important to distinguish between probability sampling in theory, which has strong theoretical guarantees, and probability sampling in practice, which offers no such guarantees and depends on a variety of statistical adjustments.
The main difference between probability andnon-probability sampling is that with probability sampling everyone in the population has a known probability of inclusion.
In conclusion, this section has provided a model for probability sampling with non-response and shown the bias that nonresponse can introduce both without and with post-stratification adjustments.
Although both approaches were used in the early days of sampling, probability sampling has come to dominate, and many social researchers are taught to view non-probability sampling with great skepticism.
For the year 2005, Germany shall supply data of which 25% shall be based on probability sampling and75% shall be based on quota samples, the latter to be progressively replaced by random selection so as to achieve fully representative probability sampling by 2008.
These new approaches can be used with either probability samples or non-probability samples. .
Cross-sectional and longitudinal data shall be based on nationally representative probability samples.
First, as probability samples have become increasingly difficult to do in practice, the line between probability samples and non-probability samples is blurring.
In addition to post-stratification, other techniques for working with non-probability samples-and probability samples with coverage errors and nonresponse-include sample matching Ansolabehere and Rivers 2013;???
By way of exception to paragraph 1,Germany shall supply cross-sectional data based on a nationally representative probability sample for the first time for the year 2008.
In particular, they used post-stratification,a technique that is also widely used to adjust probability samples that have coverage errors and non-response.
It is important that the volunteers do not need to be a probability sample from any population;
