Evil Eye Monster via Twitter asked:
How do you analyse data without having a presupposition of what you're actually looking for? Because that's important too. You're actually biasing the search system.
Steven - Actually, different people can look at the same data set and try and find different information from it. So, itís not necessarily one approach. Different people will try and tease out different bits from the same data source.
One can certainly crunch data to look for something that is significant. But, there is often a fallacy in doing it that way. They say that a good statistician can prove anything!!
