Analysis and interpretation of the data

This is an important section. It normally contains the most ‘geography' in the investigation. In other words, you need to apply your knowledge and understanding of the topic to help you describe and explain the primary and secondary you have collected. In doing this, you should always steer your analysis towards your investigation question/hypothesis. 

Data analysis 

Once you have displayed your data graphically, use a statistical technique to investigate your results for particular relationships or differences. This will help you answer your geographical question with greater confidence. Any conclusion you later make is likely to be more reliable.

Descriptive statistics give a view of the typical or average situation. Mean, mode and median give quick results. The range and standard deviation may tell you more about the spread of data.

Mann-Whitney U Test can be used to test for differences between two sets of data.
Spearman Rank Correlation test can be used to see if there is a significant relationship between two sets of data.

Interpretation of the data

This is the stage of any enquiry where you need to find out what your results tell you about the topic you have investigated. It should include the following:

A description of the spatial distribution of the information you have researched referring directly to your data (particularly maps).

A description and attempted explanation of any differences in the numerical data you have collected (e.g. why one area is different from another).

Identification of any relationships that might exist between data.

It is likely that you make several "mini-conclusions" relating to each strand of your investigation. Reference to some geographical theory should be made at this stage.
