On the first day of Christmas

Prompted by

and with apologies:

On the first day of Christmas
My true love gave to me
A testable hypoth-e-sis

On the second day of Christmas
My truelove gave to me
Two sample means
And a testable hypothesis

On the third day of Christmas
My true love gave to me
Three peer reviews
Two sample means
And a testable hypothesis

On the fourth day of Christmas
My true love gave to me
Four scatter plots
Three peer reviews
Two sample means
And a testable hypothesis

On the fifth day of Christmas
My true love gave to me
FIIIVE SIGMAA RuuuuLE

(I always thought the carol went down hill from there)
