To really analyze data and draw a conclusion you need to understand the limitations in your data. If you are interested try this book. Dark Data: Why What you Don't Know Matters, by David Hand. I really enjoyed it and marked a few pages to refer back to in my work.
It starts with his neighbor pouring white powder on his street in London. When he asked the neighbor what the powder was his neighbor said "Elephant Repellant". When he said there are no elephants here...his neighbor replied "yes see how well it works!". What we don't know is very important to the conclusions we arrive at...is the neighbor wrong?
For a text book it is really a fun read, non stop examples (I don't remember that being true of any of MY college textbooks!)
Fly fishing is completely filled with "dark data".
