It is often a good idea to choose small samples (eg for case studies) in this way; for larger samples, the random or stratified methods are likely to produce more representative results.

Random selection prevents from arising bias as opposed to non-random selections (purposive or quota sampling). However, a random selection may not always be required, e.g. in such cases where the samples are small and the sample data will not be extrapolated to …

Two categories: probability and non-probability sampling Non-probability – elements are chosen by non- random methods Probability - every member of the target population has a probability higher than zero of being selected for the sample – more likely to result in a representative sample

Random sampling is a common form of probability sampling. Non-probability sampling is not random – instead individuals are chosen based on some characteristic like being in the right place at the right time (convenience sample) or being part of a social network (snowball sample). There are more probability sampling options other than random ...

Option 2 – Non-Statistical Sampling . Haphazard sampling is similar to random sampling except it does not require a specific sample size and cannot be relied upon to form any conclusions on the population (overall number) of files. Note that haphazard sampling is often used in industry, in quality assurance audits (e.g., ISO 9000).
