So we call this the first quartile, the second quartile, the third quartile and the fourth quartile.

And we hooked up with some people studying how much variation is there between teachers, between, say, the top quartile the very best and the bottom quartile.

This is where you'll find the lower quartile, the median and the upper quartile.

These two elements over here are called the lower quartile and guess what the upper quartile.

What are the characteristics of this top quartile?

The formula is we have to four quartiles, 4 times n plus three separating elements the lower quartile, the median and the upper quartile.

When I ask you the obvious question now give me the lower quartile, the median and the upper quartile in these three boxes over here.

So, it's simple. All you need are those top quartile teachers.

What's interesting from now is I applied the quartile removal method.

We're actually splitting all the data into four groups this we'll call the first quartile, so I'll call it Q1 for the first quartile, maybe I'll do 1Q.
