In opposition with the Interpretive the Post-positivist assume that thereis an objective unknown reality which can be discovered,they maintain a distant and impartial position with the object of study to eliminate any possible bias.和后实证主义认为的形式上的目标未知的世界不同，他们对研究对象保持一个遥远的和公正的立场，以消除任何可能出现的偏差。
Post-positivism may be applied to the social world on the assumption that‘the social world can be studied in the same way as the natural world,that there is a method for studying the social world that is value free,and that explanations of a causal nature can be provided’(Mertens,2005,p.8).The Post-positivist paradigm is very frequently associated with deductive or descriptive approaches and delivers a single type of reality,either the hypothesis are rejected or are confirmed.
As a consequence from the application of this type of approach the quanti-tative findings in this report are exposed in a formal and objective style whilespace for the researcher own elaborations will be reserved to the conclusionsand recommendation sections.
Post-positivism,however,relaxes the extreme determinism of positivismby accepting that theories are provisional and that new understandings maychallenge the whole theoretical framework.Table 5.1 shows the differentrole that that the Post-positivist and Interpretivist paradigms play in theresearch and how the final data merger and interpretation will take place ina Pragmatic framework.
