ABSTRACT
The validity of the results is an important concern for any empirical study. The results of any empirical research must be valid for the population from which the samples are drawn. The samples are derived and generalized to the population that the researcher decides. Threats reduce the applicability of the research results. Hence, the researcher must identify the extent of validity of results in design stage and must also provide a list of threats to the validity of results after the results have been analyzed. This will provide the readers complete information about the limitations of the study.
