Aspects of the Literature Review

Should be well-argued & critical evaluation of particular subject. Should show width and depth of reading relevant and appropriate literature. Not sufficient to read two or three papers. Remember triangulation. Should focus clearly on particular issue being looked at. Should learn a lot about subject and will help give clearer focus on questions to ask. Should be coherent piece of […]

Triangulation

Need significant body of evidence to support hypothesis. If taken from literature, read extensively around subject and gather wide range of correlative sources. If evidence is from own work, number of data sets required from different circumstances to ensure experiments/observations are repeatable. This approach is called triangulation – sets of evidence from various sources supporting same hypothesis required to reach […]
