But, your finding was based on actual experimentation.
They usually are. In fact, anything that's presented as a finding that's
not based on measurements, or a survey, or observations of some kind isn't a finding at all, but an opinion.
Why wouldn't the range be considered factual and not merely a finding?
The range -
within that sample - is factual. But it's not enough to make a factual statement about all tapeworms everywhere. (The longest one I've personally seen was well over a meter.)
So, there might be a whole lot of facts about a whole lot of subjects, but they don't necessarily add up to a factual
conclusion about the entire of class of entities under study.
The writer of your article can present a series of facts that were recorded during his study and let you draw a conclusion. What he can't do is present his own conclusion as a fact.
Not trying to be obtuse, this is something I'd like to better understand.
Scientific research is fussy and tedious. It takes a pile of little facts - measurements, usually - to make a finding and several findings to make a theory, which then has to be tested, usually through one or more experiments devised especially, and preferably by different teams, attempting to show up exceptions and contradictions, before it's an
accepted theory. And even then, it has years of challenges to survive before it's generally stated as a fact.
Think climate change. How many ice-cores, how many wind-speed measurements, how many rainfall comparisons; how many findings in how many lonely fields stations; how many computer models and simulations, symposia and conferences, add up to the one really big, freaking FACT?
Can something be a finding and a fact?
It depends on the question. A big question needs many findings to verify it; a little one may get by on a single study....
No, on second thoughts, I don't think it can, because every study has a potential bias or blind-spot or inadequate sample source. Every finding requires independent corroboration.
