First things first

Well, firstly, your analysis will be incorrect. Without analytically correct analysis, what essentially you will be doing is analysis of patterns. But, in order to make deep conclusions you have to take that raw data and perform some data conversion based on physics, and then analyze that data. 

Here is your pool of sand!

For example, if you have a swimming pool of sand and a few gold grains in it, you will never find it by scooping it with your hand. You could use a sieve, but you are summing you don’t have a lot of rocks.

What you need is a metal detector. Correct use of analytical tools/equation/experimental setups result in a heightened super sense of detection. Without this, your efforts to solve deep issues will just kick up dirt.

Also, non-filtered data is more susceptible  to variability, error in measurement going undetected, and underlying patterns going unnoticed, and lack of data cohesion.
