Another interesting fact is that it is almost impossible to cite the number of groups and the type of groups until the research is completed.One problem with this type of sample is that volunteers might be different on certain variables than non-volunteers, which might make it difficult to generalize the results to the entire population.Initially, theoretical sampling is used only for a pragmatic purpose of generating a theory.
