There are a number of reasons that can be attributed to this. In the first place, the unique characteristics of the research setting where the case study was carried may be difficult to find in other areas and so applicability of findings in other context becomes challenging (He and Opposs, 2012). Again, most of the variables in case studies have been noted to change very rapidly with time. This is another condition that affects that applicability of case study findings negatively.
On historical researches, Gall, Gall and Borg (2007) noted that there are very specific components of these that make them unique from other forms of research. More importantly, the approach to conducting historical research has been said to be an important factor that affects outcomes. To get very accurate outcomes that can be considered applicable to present situations, it is admonished that there will be the extensive use of primary resources of data for historical research. The idea is that using primary sources of data makes it possible to have evidence that justify the occurrence of events in the historical contexts within which the research is performed (Dorn et al., 2013). For example to undertake a historical research on the abolition of slave trade, it will be important to use such primary sources of data such as books or newspaper articles that were produced at the time of the event. Doing so helps in finding the real validity behind the claims that are made in such ...Show more
