I've heard that data analysis is an art-- with the same data, two different analysts can paint two completely different pictures.   My style is quick, reliable, and pretty.   I first cleanse the data to make sure that there are no outliers or missing data. Afterwards, I check the data types and look through the data to make sure I know what I'm working with.  I usually use Tableau to do the analysis, but it can be done in any preferred tool.  Finally, I make the finishing aesthetic touches so that you can look at something that's easy to read, modern, and beautiful. And I'm always on time. I've got a reputation to uphold :)
