“Estimation statistics” is a fancy way of saying that you are estimating population values based on your sample data.  Let’s think back to our sample ice cream data.  First, let’s assume that we had a true random sample of 35 people on this globe and that our full target population is every human alive (7 billion people).  Let’s say that 37% of people in our sample said that vanilla is their favorite flavor.  Can we safely extrapolate that 37% of all people in the world also think that vanilla is the best?  Is that the true value of the world?  Well, we can’t say with 100% confidence, but–using inferential statistical techniques such as the “confidence interval”–I can provide a range of people that prefer vanilla with some level of confidence.

Showing :
When I see birches bend to left and right
Across the lines of straighter darker trees,
I like to think some boy's been swinging them.
But swinging doesn't bend them down to stay.
As ice-storms do. Often you must have seen them
Loaded with ice a sunny winter morning
After a rain. They click upon themselves
As the breeze rises, and turn many-colored
As the stir cracks and crazes their enamel.
Soon the sun's warmth makes them shed crystal shells
Shattering and avalanching on the snow-crust
Such heaps of broken glass to sweep away
You'd think the inner dome of heaven had fallen.
They are dragged to the withered bracken by the load,
And they seem not to break; though once they are bowed
So low for long, they never right themselves:
You may see their trunks arching in the woods
Years afterwards, trailing their leaves on the ground
Like girls on hands and knees that throw their hair|
Before them over their heads to dry in the sun.
- excerpt from "Birches" by Robert Frost
