What are the processes of sampling?
Sampling can be done through probability (random selection) or non-probability (non-random) technique. Now, if the sampling frame is approximately the same as the target population, random selection may be used to select sample.
What are some common issues with sampling?
In general, sampling errors can be placed into four categories: population-specific error, selection error, sample frame error, or non-response error. A population-specific error occurs when the researcher does not understand who they should survey.
What is the purpose of sampling process?
The primary goal of sampling is to create a representative sample, one in which the smaller group (sample) accurately represents the characteristics of the larger group (population). If the sample is well selected, the sample will be generalizable to the population. There are many ways to obtain a sample.
