Final answer:
The correct type of sampling for obtaining a population where composing a sampling frame is severely inhibited is Purposive sampling. Convenience sampling could also be suitable, but it is less reliable. Cluster sampling and quota sampling are not suitable.
Step-by-step explanation:
The correct type of sampling for obtaining a population where composing a sampling frame is severely inhibited is Purposive sampling. Purposive sampling is a non-probability sampling technique where the researcher selects individuals based on a specific purpose or criteria, rather than random selection. This type of sampling is often used in situations where it is difficult to create a sampling frame such as in qualitative research or when studying a unique population.
Another type of sampling that could be suitable in this scenario is Convenience sampling. Convenience sampling involves selecting individuals based on their availability and willingness to participate in the study. However, convenience sampling is generally considered less reliable and less representative of the population compared to other probability sampling techniques.
Cluster sampling and quota sampling are not suitable in this case. Cluster sampling involves dividing the population into smaller groups or clusters and randomly selecting some clusters to be included in the study. Quota sampling involves selecting individuals to match certain characteristics or quotas set by the researcher.
