How to avoid sampling bias?
- The most effective way to avoid sampling bias is to select a random sample. Also, we try to avoid other possible sources of bias by considering things like the wording of a question. The key is to always think carefully about whether the method used to collect data might introduce any bias.
What is the problem of publication bias bias?
- This issue is made even worse by the fact that usually only signi?cant results are published. This problem is known as publication bias: Usually only signi?cant results are published, while no one knows of all the studies producing insigni?cant results. Consider the umbrella example.
Can caller ID bias the sample?
- Like- wise, people with unlisted numbers who are not contacted could also bias the sample (discussed in the next chapter), and hence, the data obtained. With the introduction of caller ID, it is possible for telephone interviews to be ridden with complexity.
What is non-probabilistic sampling?
- The most widely used method of non-probabilistic sampling is quota sampling. Sampling will often be the only feasible method of obtaining data, quite apart from questions of time and cost.
