How can I find evidence-based assumptions in a variable-based industry?

[billingtame]

Hello, I come here not as a physicist, but in search of one (or more). One thing I lack is evidence based assumptions when dealing with a variable based industry. So, I come to poke the minds of those who will hopefully supply me with the data I need to better make decisions in my chosen research field.
