This is where you'll find the lower quartile, the median and the upper 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 we call this the first quartile, the second quartile, the third quartile and the fourth quartile.

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

Median

Median

The median.

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

The median is 1.98.

What are the characteristics of this top quartile?

So here it's the median.

The median is also 3.

So this is the median for all of the trees that are less than the real median, or less than the main median.

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.

This line over here this is the median this right over here is the median.

And this is called the median.

What's median and mode good for?

MAD is the Median Absolute Deviation. .

So what would the median tell us?

Now we see the median is 4.

So 160,000 is the median house price.

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

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

The other very typical way is the median. And I will write median. I'm running out of colors.

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.

The median contribution was somewhere around 57 dollars.

So in this case, our median is 50.

This is better than the median, because the

There's a mean, the median, and the mode.

So the median of this set is 2.

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.

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

We'll call this the in data type of median.

The median is a bit more difficult to compute.

Resisted opposition of the thumb tests the median nerve.

The median is order statistic like n 2 floor.

And asked them, What's your score? That's the median.

Slightly more challenging to program is the function median.

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.

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

And the median is literally looking for the middle number.

That' s the median. You might make a case for.

let me just add one the median isn't exactly defined.
