Discuss Purpose of the discussion: When you conduct your dissertation, you will compile a large amount of information. This info will need to be assembled, processed, simplified, clarified, and shared in order to bring out its true value-in a word, reduced (often referred to as data reduction).Your data analysis will use statistical procedures (tools) to reduce the amount of detail in the data and summarize it, and make the most important facts and relationships apparent.

While one could hand tabulate findings, it is far more efficient to use statistical software to display results and calculate appropriate statistical analysis. This is where SPSS comes in! Even though software helps greatly to simplify the processes of computing calculations and tabulations, you will be the one to analyze and interpret the findings.
