The main disadvantage of nonprobability sampling is that it may not be representative of the population of interest. This can lead to skewed results and affects the validity of research conclusions. In contrast, probability sampling methods aim to ensure better representation and allow for calculating sampling error. ;
The main disadvantage of nonprobability sampling is that it may not be representative of the population of interest, leading to biased results. Nonprobability sampling does not allow for random selection, which can affect research validity. Therefore, the correct choice is C: It may not be representative of the population of interest.
