Hypothesis Testing is Fun!

may sing to tune of "Mr. Bojangles" (Jerry Jeff Walker)

Well, I didn't think I'd ever like statistics,
and I don't know why.
so I gave it a try.
And I've changed my mind, yes I've changed my mind,
'cause it's clear to me now,
Hypothesis testing, hypothesis testing, hypothesis testing is fun!

Oh, you state your null hypothesis and don't forget,
It may be directional that means it has one tail,
but usually two.
You decide on alpha, oh, don't forget alpha,
to control errors Type I and II.
Hypothesis testing, hypothesis testing, hypothesis testing is fun!

Then compute your z or t or F or chi-square,
and compare it to the table.
To decide the fate of your own null hypothesis,
you reject it if you're able.
If you're lucky you reject it, don't try to accept it,
it's not logical to do.
Hypothesis testing, hypothesis testing, hypothesis testing is fun!

So statistics really can be quite enjoyable,
if you study all along.
And I want to world to know about the joy I've found,
so I wrote this song.
And I hope you'll sing it, yes hope you'll sing it,
in a voice clear and strong.
Hypothesis testing, hypothesis testing, hypothesis testing is fun!
