Question

What are four ways of selecting a biased sample of a population of interest? Which subsets are more likely to be selected in each case.

Answer 1

Four ways of selecting a biased sample are: purposive sampling, convenience sampling, volunteer sampling, and quota sampling.

Step-by-step explanation:

Four ways of selecting a biased sample of a population of interest are:

1. Purposive sampling: intentionally selecting individuals who have characteristics that align with a specific bias.
2. Convenience sampling: selecting individuals who are easily accessible or readily available.
3. Volunteer sampling: relying on individuals who self-select to participate, potentially biasing the sample towards those with strong opinions or motivations.
4. Quota sampling: selecting individuals to match specific quotas, which may introduce bias if quotas are not representative of the population.

In each case, certain subsets are more likely to be selected. For example, in purposive sampling, subsets with the desired characteristics will be favored. In convenience sampling, subsets that are easily accessible will be more likely to be selected. In volunteer sampling, subsets with strong opinions or motivations are more likely to be represented. In quota sampling, subsets that help meet the predetermined quotas will be favored.
