When it comes to bundles of joy,
Fifty one percent of births are boys.
That's so close to half
You might just laugh.
But with all the births every year,
It's statistically significant I fear!
Everything's significant for big enough n!
A thousand stations were asked,
What was their price of their gas.
The calculation went:
The mean was up by 1 cent!
Two million students took the SAT:
It's one measure of quality.
They said this year's average score
Had declined by four.
When you do a hypothesis test,
The statistic formula is expressed.
And if n is bigger that you'll see
then that means a smaller p.
Statistical significance
Only goes so far,
Find an effect size
Before you show your charts.
Three out of four dentists ain't a big deal,
But three thousand of four thousand makes that same fraction
Statistically real!
