Your literature review must be a presentation of the most relevant and up to date data based on the materials you used for your research and reference. It must be reliable, and you must give your justifications for it. The methodology chapter has to be a detail of the plan, procedure and methods used by you, like the maps, pictures, graphs, figures and statistics, etc. The findings you achieve in the end of such a method would be quantitative one. That is it will be a numeric expression based on the objective method. Hence, you need to be very careful with the figures. A small change in the actual figure can make a whole lot of difference. Moreover your methods must have scope for further implementation by future researchers.
