...if the difference isn't different enough to make a difference, what's the difference?

There are two possible outcomes: If the result confirms the hypothesis, then you've made a measurement. If the result is contrary to the hypothesis, then you've made a discovery.
Enrico Fermi (1901 - 1954)
For every fact there is an infinity of hypotheses.
Robert M. Pirsig (1928 - )
Hypotheses, like professors, when they are seen not to work any longer in the laboratory, should disappear.
Henry Edward Armstrong (1848 - 1937)
Old statisticians never die - they just become nonsignificant.
Gary C. Ramseyer (1934 - 2012)
The great tragedy of Science - the slaying of a beautiful hypothesis by an ugly fact.
Thomas H. Huxley (1825 - 1895)
It is a good morning exercise for a research scientist to discard a pet hypothesis every day before breakfast. It keeps him young.
Konrad Lorenz (1903 - 1989)
The number of degrees of freedom is usually self-evident - except for the analysis of data that have not appeared in a textbook.
David Durand (1912 - 1996).

May be sung to the tune of "Roll out the Barrel" (Lew Brown, Wladimir A. Timm, Vasek Zeman and Jaromir Vejvoda)
What's a p-value?
Test a hypothesis and see.
What's a p-value?
It is the probability,
That a new test statistic,
Would be at least as extreme as the old,
Given Ho is true.
That is what I'm told!

When I find myself with normal data,
William Gosset comes to me
Speaking words of wisdom, Use a t.
If my NP plot is linear
but sigma isn't known to me
This is not a problem, Use a t.
Use a t, use a t, use a t, use a t
Student knows the answer: Use a t.
And when the broken hearted students
in a stats class can't agree
You can show the answer: Use a t.
Some want to use a Z test,
and a chi-square is a mystery
The truth is very simple: Use a t
Use a t, use a t, use a t, use a t
Student knows the answer: Use a t.
And when your thoughts are cloudy,
RA Fisher may not hear your plea
But Gosset will deliver, with a t.
He knows you are trying
and he wants to set your mind at ease
Don't think twice about it, use a t.
Use a t, use a t, use a t, use a t
Student knows the answer: Use a t.
