Question

True or false: Sampling when there is no sampling frame is called non-probability sampling.

Answer 1

Sampling when there is no sampling frame is called non-probability sampling.- True

Explanation- In non-sampling probability, it is not possible to generate a sampling frame, and the probability that any individual is selected into the sample is unknown.

Here the odds of any member being selected for a sample cannot be calculated and it relies on the subjective judgement of the researcher.

For example- In convenience sampling (part of non- sampling), we select individuals into our sample based on their availability to the investigators rather than selecting subjects at random from the entire population. As a result, the extent to which the sample is representative of the target population is not known
