The analysis process is both an art and a science. The pre-analysis steps of loading, surveying, and transforming data are a well-defined process that prepares the data for the analysis. The analysis itself, however, is a creative process whereby the investigator matches the requirements of the investigation to the data in order to determine which analyses should be performed. Many different types of analyses can be performed, and it is up to the investigator to identify which techniques should be applied in order to build the case and arrive at the findings.
The next chapter will cover how to present the analysis findings and how to provide a clear and compelling case based on Big Data evidence.
