# Confidence Rap

Lyrics & Music © 2019 Parker Kain (Lil P-Value)

Confidence, know it is common sense
Any good estimate gotta have consequence
Unless your sample is as big as the populace

Ooh, tryin get a better idea of
Mu, that’s the situation we gon
Pursue, so take a sample that’s the first thing to
Do, now we got insight we’re gonna

Accrue, we could also guess at p
Population proportion I mean,
Categorical data we need,
But the processes they all agree

Now we got a center, and we gotta formulate
margin of error, know we gotta calculate
So we take our deviation , and our sample size
Put the two together and we multiply it by our

Confidence, Confidence, Confidence, Confidence
Confidence, Confidence, Confidence, Confidence
Confidence, Confidence, Confidence, Confidence
Not backed up by stats call that data incompetence
The way we do math, you know we got confidence

(Repeat)

To make a point you gotta get a point
We’ve got the error now we case the joint
99? Maybe 95?
Percent confidence, we gotta decide

Get associated z score
Multiply it by error to be sure
Points of data need context, or else
I’ll be lookin like Eeyore

Take the, point, and we add subtract the error
Got two, bounds, ones the greater ones the lesser
What’s the story though? The point of this endeavor?
need some context, it’ll make the insights better

Confidence, knowledge is bottomless
Stats is the answer to relevant problems
Hunches are old keep those up in sarcophagus
Data is filling up all business documents

Got it? Good. Got two points and it
Understood. Given many samples that the
Margin would capture the parameter the
Likelihood, is all based off of our

Confidence, Confidence, Confidence, Confidence
Confidence, Confidence, Confidence, Confidence
Confidence, Confidence, Confidence, Confidence
Not backed up by stats call that data incompetence
The way we do math, you know we got confidence

This ain’t 101, man I sleep on Z’s
But I’ll drive home a T-test put it on the green
I mean it when I say I’m above the mean
Not standard, deviation’s way past 3

Know we’re not normal, when it comes to clout
It’s chi, not chai, if you ever in doubt
I’m at outlier, but you can’t you can take me out
-

You never gonna see me in the back of the class I attack a
mathematical model you bet I be accurate when it
comes to stacking knowledge I’m a chronic insomniac Givin
me a tiny sample I’m bootstrapping it and When the data

messy I’mma janitor Programming up in R until I
