For a population, there is a parameter

We want to learn about it, it's the number that we're after

Our best guess for its value is the sample statistic

The method we use to get it should make us optimistic!

We'll estimate proportions from opinion polls

Or estimate the mean height from our class rolls.

We hope our sample targets the parameter unknown;

We want a likely range stated as a zone.

When we seek that interval, it's always good to know

What would make it shrink and what would make it grow.

The interval gets tighter with increasing *n*:

The added information helps us narrow in!

The interval gets bigger with a larger *s*,

That has come from a sample that's a more uncertain mess!

The interval gets wider for higher confidence

'Cause you have to cover lots more of your bets!

Our sample gives us one shot to make a decent guess

So let's use a method with a high rate of success!

I'm eighty percent confident my answers are first rate,

In my estimation, when we estimate!
