Oops! ... I Picked The Wrong Test

Lyrics © by Jen Simonds
may sing to tune of "Oops! ... I Did It Again" (Britney Spears)

I think I did it again
I made you believe,
I had what I need
Oh, Chuck, I have run a Z-test,
But that doesn't mean I know what's best
But to lo-ose my σ, that is just so typically me
Oh baby baby

Oops I did it again
I picked the wrong test
Got invalid results
Oh, baby baby
Oops I ran a two-tailed
When I wanted just one tail
For my hypothesis

You see my problem is this
I'm running t-tests
Wishing my groups they were independent
I cry watching the curve
'Cause if I reject, I've got nerve
But to lose degrees of freedom
That is just so typically me
Oh, baby, Oh baby baby

Oops I did it again, I misread the graph
Where's the interaction?
Oh, baby, baby
Oops, are those parallel lines
And where are the main effects
Is this even an ANOVA?

[Dream Sequence]
Chuck: Britney, Britney, I got these for you.
Britney: But I thought the old lady archived these down in the basement of the library
Chuck: I went down and got them for you.
Britney: Awww, you shouldn't have...
Chuck: No, you really need these

Oops I ran a Pearson's for my test
I tried to correlate categories
Oops you think that I needed a Χ²
For my nominal data

Oops I did it again, rejected the null
Didn't understand p
I thought bigger's better
Oops I misread the "sig."
On my SPSS output
I'm not that innocent

Oops I did it again
I picked the wrong test, got invalid results
Oh, baby baby
Oops I ran a two-way
When I wanted a three-way
For my hypothesis.
