Explain how to determine if a probability-based sampling is necessary for a given research study.
Probability-based sampling is necessary for research when the researcher needs the sample to be a representation of the whole population. In a probability-based sampling, each sample has an equal chance to be included in the sample for research and there is no bias in this method of sampling.
