Statistically significant
Happens when your observed
Is so far away
Far away from expected
There’s not really a way
That’s the sample I got
Happened because
Of chance, because of chance
Sampling variability
Sampling variability
Happens because you got
Different data than me
Oh if my observed sample’s
In the rejection region
Then the data that I got’s
Statistically significant

If the p-value is low
If the p-value is low
The null hypothesis has to go
If the p-value is low
If the p-value is low
The null hypothesis has to go

may sing to the tune of "Brown-Eyed Girl" by Van Morrison
Do you remember when we used to sing…
The p-value is the probability
Of getting this sample
Or something more extreme
If the null is true
The p-value is the probability
Of getting this sample
Or something more extreme
If the null is true

Well you can tell by the way some do a test
They’re just lookin’ for values blessed;
Draw a line and guard it strong
Against an error of Type One.
With point oh-four-nine, it’s okay: Their work may see the light of day.
We can try to understand what makes results significant.
Z of more than 2 lets shaded tails accrue below point-oh-five, point-oh-five.
That’s what Fisher mused so everybody used point-oh-five, point-oh-five.
Ah, ha, ha, ha, point-oh-five, point-oh-five
Ah, ha, ha, ha, point-oh-fiiiiiiiiiiiiiiiiive
