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

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

If you remember this method, you realize there were four quartiles, and individual elements separate those.

Let me do this here, there's two of age 19, 3 times the age 22, two aged 23, 24 and 25 and now we can call this at exactly 11.

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.

Let me ask you a question.

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.

And this will be a 15 from reads 19, 23.

And all the test cases we'll be using will have the property that the lower and upper quartile are well defined elements.

The answer is 83.

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

What I want you to do is to now code a piece of software called calculate_weight that has 3 things, and I think you can do all three of them yourself.

Steven's actual data against the background of all other patients, against this information.

It will end in my being conveyed into the house.

Quarter note. Half note.

The hardest part is to get the outlier removal correct.

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

We have 163 samples.

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.

Four...

What I mean by that is, imagine that these two guys are position vectors that are specifying points on a parallelogram, and then of course the or not of course but, the origin is also another point in the parallelogram, so what will be the last point on the parallelogram?

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

each of the bank notes might look something like this

They are doing that on a quarter of the resources that are used typically in the

It turns out even if it doesn't factor nicely, those give me good numbers.

About a fourth of the trees end up here, a fourth of the trees are between 14 and 21, a fourth are between 21 and it looks like 33, and then a fourth are in this quartile.

Now, 163 3 special elements makes 160, divided by 4, makes each of these 40.

I'll go with 21. gt gt 21!

We analyze in four dimensions.

Four...? Make it quick. This cell is running out of juice.

Let's start with a square that has area of one meter.

First of all, there's the quarter note...

The third quarter.
