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

Much like ranking ranking pain, I want you to think about ranking gains.

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.

So then here's the final ranking.

What are the characteristics of this top quartile?

They will kill you regardless of your ranking.

Even a higher ranking official would be killed.

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.

There are few high ranking positions left open for you.

Not like ranking top, just better than the previous one

And what you will find is a very, very low ranking bitch will quite easily keep a bone away from a high ranking male.

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

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

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.

He is indeed one of Our high ranking, firmly believing bondmen.

He is indeed one of Our high ranking, firmly believing bondmen.

Indeed they are two of Our high ranking, firmly believing bondmen.

He is indeed one of Our high ranking, firmly believing bondmen.

Man Architect? I've heard about him he's a top ranking architect.

Well, unfortunately there's no international ranking tables for teacher feedback systems.

This is a common ranking system we use in Japanese arts ,

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.

My dad was a high ranking gang member who ran the streets.

and 20 high ranking officers will appear speaking against the Chávez government,

So, each quartile, since we have four of them has exactly two elements.

And then I compute a new data set where I just extract data in the range from the lower quartile to the upper quartile using this simple command over here.

The high ranking government official ruled out the possibility of a general election.

The output is going to be the highest ranking page with that keyword.

For meijin, we have this league system called jun i sen , ranking league .

For that I sorted the data and I computed the lower and upper quartile.

In the OECD survey, northern European countries are keeping their high ranking in tax rates.

Holly, a hologram I may be, but I'm still the highest ranking technician aboard this ship.

First, I want you to remove the outliers by only extracting data between the lower and upper quartile.

You did it. Professor Mitchell from Carnegie Mellon University with us today computed the quartile of this data sequence.

This one's called the median, the lower, and the upper quartile, and these guys are the ones being picked.

And in fact this range in between the upper quartile minus the lower one is called the interquartile range.

It turns out the number of data points make it well defined what the lower and upper quartile is.

And since I am the ranking officer if you don't like it, I believe you can go to hell.

After cleaning up and removing the points outside the quartile range, what do you think the new mean will be?

Detroit has consistently ranked in the Top 10 Most Dangerous Cities in the United States, oftentimes ranking at number one.

Okay, so you throw away the extremes, you arranged all points as before minus 99, 13, 17, 33, 1489, we find that these are the lower quartile and upper quartile, this happens to be the median these are the numbers that are average 13, 17 and 33.

You're not just like, quote,quote, quote, quote, quote with no other ranking or attribution or insight or research or whatever.

All right, in the next video, I'll explain about woman professional players and amateur players, and their ranking systems as well.
