It's not a flawed example. As you can understand from the other poster talking about baselines.
> Its not that hard to grasp.
I agree!
> Like in the video you posted he pretty much needs to have some kind of fluid through the process.
And it looks like you're understanding too!
But if he used a different process he could have used it dry. There's a lot of ways to skin a cat. Different ways create different constraints.
So I'm confused here, did you just want to argue or did you actually want to understand? Because at this point it seems like you understand. And frankly, I don't want to argue
Sure seems like you do with all your passive aggressive takes of asserting I'm confused or can't read or can't understand things and that I lack understanding the most basic scientific concepts like null hypothesis testing.
My question was simply:
> But how do you know your source of distilled water isn't also contaminated?
You could have just replied with "you don't, and it doesn't always matter depending on the questions being asked and the processes being used" but instead you've drawn it out to this many comments.
Instead you chose to say "you read the rest of my comment" instead of actually answering my question and then talk down to me over and over.
Some of the other comments seemed to be acting like running a blank is a fool proof way to just make sure you get a clean answer, and my point was to show there are still limits to "just run a blank". And that's shown by the sibling thread here with the other poster thinking if your blank has 100 particles and your test sample having 101 that means the test process obviously introduced the particles, which is a flawed understanding of the results of the test. The results are inconclusive, it did not prove the sample contained no particles to start.
But if he used a different process he could have used it dry. There's a lot of ways to skin a cat. Different ways create different constraints.
