Like the resources researcher earlier, only phenomena that you can observe will lead to the production of credible data. To generate a research strategy to collect these data you are likely to use existing theory to develop hypotheses.
Bryman and bell (2007) investigate that positivism is an approach that supports the application of the natural sciences to the analysis social beyond and reality. Saunders et al. (2009) agree with previous study that describe positivism is only phenomena that the author can notice will reach to the result of credible information. Furthermore, the researcher can apply existing theory to improve hypotheses.
