Decile
Categories: Metrics
In statistics, a decile is a method of dividing a data set into ten equal groups. It provides a way of organizing data so it can be analyzed more granularly.
We'll explain it by taking a detour through a more common example of the same type of calculation. A percentile divides a group into 100. So if you take the SAT, you might discover you scored in the 95th percentile. Solid score. Major school bound.
A decile makes a less fine distinction. In the SAT case, you'd find yourself in the 10th decile, or top tier.
The decile became a point of contention in company management. The once-popular former GE CEO Jack Welsh advocated firing the bottom 10% of employees each year.
Another way of saying this: He wanted to eliminate the bottom decile.

Finance: What Is a Basis Point?124 Views
finance a la shmoop what is a basis point?
well one percentage point is a hundred basis points, half a percentage is 50
basis points, five percentage points is? yeah we're gonna make you do that one on [frowning man talks to camera]
your own. well the basic idea is that in very large financial transactions those
involved need highly granular computation grids, and basis points
divid interest rates much more tightly. if a company borrows three billion
dollars just noting that the rate is four percent is really vague. it would
need to be noted as four point zero zero percent. why? because just one basis point [equation on screen]
i.e. one hundredth of a percent per year on three billion dollars borrowed
is still a lot of money. that is one basis point on three billion bucks is
300 grand .so basis points are a real thing in high finance transactions and [smiling man talk to camera]
okay okay the answer is 500 basis points. yeah all right now you can go back to
spinning this thingy. [man spins fidget spinner]
