____ sampling is a good method to use when conducting a pilot study.
A
Non-probability
B
Non-probable
C
Non-random
D
None of the above
Explanation: 

Detailed explanation-1: -Non-probability sampling is most useful for exploratory studies like a pilot survey (deploying a survey to a smaller sample compared to pre-determined sample size). Researchers use this method in studies where it is impossible to draw random probability sampling due to time or cost considerations.

Detailed explanation-2: -Convenience sampling (also known as grab sampling, accidental sampling, or opportunity sampling) is a type of non-probability sampling that involves the sample being drawn from that part of the population that is close to hand. This type of sampling is most useful for pilot testing.

Detailed explanation-3: -Common non-probability sampling methods include convenience sampling, voluntary response sampling, purposive sampling, snowball sampling, and quota sampling.

Detailed explanation-4: -Probability sampling is used when the research is conclusive in nature. On the other hand, when the research is exploratory, nonprobability sampling should be used. The results generated by probability sampling, are free from bias while the results of non-probability sampling are more or less biased.

Detailed explanation-5: -Non-probability sampling designs are used when the sample needs to be collected based on a specific characteristic of the population (e.g., people with diabetes). Unlike probability sampling, the goal is not to achieve objectivity in the selection of samples, or to make statistical inferences.
