I have developped three-evolution-step for data analysis at practical work spaces.
Many companies are in the second step and stops its activity, where you just summarize and/or visualize the raw data.
But this is NOT “data-analysis” but is “data-summary” to get the overall picture of the past result(s).
Data analysis is someting different from it. It helps you find general characteristics BEHIND the original data.
You need to learn how to move one more step forward when you want to apply the data analysis to your daily jobs.
