may sing to the tune of "Take Me Out to the Ball Game" (Jack Norworth and Albert Von Tilzer)
Take me out to the brew'ry,
biggest one in the world:
Guinness used data to lead the pack--
boost the taste and keep costs on track!
But with few, few samples for testing,
mean's error was so unexplained:
then came William Gosset's result
under Student's name!

may sing to the tune of "Barbara Ann" by Beach Boys
Type II Error
Type II Error
Type II Error
Cause me to fail to reject
The false null hypothesis
Type II Error
Type II Error
No Evidence
No Evidence
No Evidence
Cause me to fail to reject
The false null hypothesis
Type II Error
Type II Error

may sing to the tune of Queen's "We Will Rock You"
If the null is really true and we get a sample
That causes us to reject the null,
That’s a Type I Error
Type I, Type I Error
Type I, Type I Error
Repeat

may sing to the tune of "Star Spangled Banner"
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

may sing to the tune of "Hound Dog" by Elvis Presley
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
Lyrics © Mary McLellan
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
