ANOVA Man
Words: Mark Glickman
Music: Lennon/McCartney ("Nowhere Man")
He's a real ANOVA man
Designing all his sampling plans
Calculating mean-squared errors and p-values.
Wants to test for equal mu's
Knows which tables he must use
All his samples he will choose at random.
ANOVA man, please listen;
Where's the data that you're missing?
ANOVA man, what kinds of bias can you withstand?
Writes down two hypotheses;
Hopes to reject the first of these;
Needs to list out all degrees of freedom.
ANOVA man, try harder;
Don't give up, you're smarter;
ANOVA man, how come your students don't understand?
At 0.05 he rejects
Ignores the size of his effects
Now he's stuck -- he's got selection bias!
ANOVA man, please listen;
Where's the data that you're missing?
ANOVA man, what kinds of bias can you withstand?
He's a real ANOVA man
Designing all his sampling plans
Calculating mean-squared errors and p-values.
