Many people tend to jump into analysis when getting data at the issue.
The end results are always:
1) spending so much time
2) do not reach any conclusions
3) find an answer but not for the original issue…
What makes those people spend so much time for “nothing” is lack of hypothesis BEFORE going into analysis.
Making hypothisis will make you analysis more effective and efficient in the following ways:
a) Identifying fundamental goal/objectives,
b) hence, you may easily and properly find “right” data and “right” method for the analysis
c) also you do not need repeat unnecessary analysis
d) finally you can make a robust storyline from the beginning, which you may use for presentation of the analysis results
Please keep this in mind and try to make your hypothesis BEFORE starting to play around the data!
