Okay, I made a song.

I will sing it for you tomorrow.
It goes to the Adam's Family theme song https://www.youtube.com/watch?v=_YFk4b6yeX4

Here are the lyrics

Verse One:

The data fit (clap clap)
The data fit (clap clap)

When data we collected
Match the unexpected
Our hypothesis is rejected
We don't reject the null.

A chi square that is smaller
Shouldn't make you holler
The null is still the baller
We don't reject the null.

Critical value (clap clap)
Critical value (clap clap)

When data we collected
Match the unexpected
Our hypothesis is rejected
We don't reject the null.





If you can learn this song, then you know, that if the data doesn't fit, (high chi) we reject the null.
