Lyrics:
[Intro] Two worlds colliding, one truth dividing. Is it frequency or is it belief? Let’s break it down—no winners, just vision. Drop the beat!

[Verse 1: The Frequentist Unit] I’m looking at the long run, hypothetical repetitions. Treat the population mean like a constant, unknown but fixed. But the sample data? That’s where the randomness begins. I’m building sampling distributions, imagining the study repeated over and over again. I do hypothesis testing, put the theory to the test. Assume the Null is true 'til the p-value hits the floor. That’s the Frequentist way I know!


[Pre-Chorus] One side sees fixed, the other sees random. Who’s the one providing the most clarity? Two different lenses, but both are valid. Quantifying uncertainty is the name of the game.

[Chorus] Frequentist or Bayesian? We’re living in the tension! Two schools of thought in a statistical dimension. No one takes the throne, no one’s left in the cold, It’s just a different story that the data has told. Dual perspective, pick your favorite lens!


[Verse 2: The Bayesian Unit]I don’t need a million trials just to find what is real, I start with a Prior—how the world makes me feel. To me, the parameter is the thing that is random and shifting, Through the clouds of uncertainty, I’m constantly sifting. I update my view as the evidence grows, Bayes’ Theorem guides where the probability flows. The Posterior is the prize, the truth I design— That’s the Bayesian state of mind!


[Bridge: Rap Battle Style] Frequentist 95% Confidence Interval! Over many repeated trials, 95% of my intervals will catch the prize. The parameter is fixed; it’s the endpoints that are random.

[Bayesian] But is that intuitive? Not for me! Give me a Credible interval, 95% chance. That the parameter is right here, in this specific credible interval. It’s more intuitive, that’s what people tend to think.

[Together] Different definitions, but we’re here to stay!


[Chorus] Frequentist or Bayesian, we’re living in the tension! Null hypothesis testing or Bayes Factor? In this statistical battle, no one sits on the throne. Both paths are valid, yeah, we’re finding the way. Dual perspective, pick your own favourite!


[Outro] Repeatable events... or a belief in the soul. Two different ways to stay in control. Is the truth in the many? Or the truth in the one? Either way you calculate... The analysis is done.
