Which one is called non-probability sampling?
a) Cluster sampling
b) Quota sampling
c) Systematic sampling
d) Stratified random sampling
The answer is Quota sampling
In general, quota sampling is used when the sample size is not sufficient to capture the desired level of statistical significance, where the response or distribution of a survey variable differs from that of the population. A simple example is where a trial in a laboratory experiment with different groups of animals gets too small to produce an estimate. In this case, we choose a random sample and try it out to see if any difference.
The right answer is Quota sampling
Non-probability sampling (NPS) is an approach to making statistical inference that can be used when the sample size is unknown or too small. NPS works by randomly assigning distributions to each observation in a sample and then measuring how much of the distribution of each observation actually occurs.
