Let's label all the valves.

One will be the tricuspid valve and the other the mitral valve.

No shark teeth, Pop.

A church spire could be seen in the distance.

And there were glowing arrows on the ceiling.

In certain countries, mosque minarets are being banned.

Teeth filed to fangs.

When the valves snap shut, for example the tricuspid and the mitral valve snap shut, well, that makes a noise.

You can take a guess as to which ones I'm referring to. Atrioventricular valves are the two valves between the atria and the ventricles.

So this valve is called the Tricuspid valve.

You'll hear S1 when the tricuspid and the mitral valve snap shut. So far so good.

These valves shut down like that.

FALCONER'S SHlPWRECK.

lecture two. We just have the mean, the standard deviation, the median, trimmed mean and so on. Here's the skew, here's the kurtosis.

Cubic Curve with Cusp by Four Points

She had these teeth. Never seen anything like it. Practically bit a man in half.

No surprise, just as before, if that's S1, this is S2.

But the view from Van Gogh's window stops short at a wall.

Her manner of speaking gets on my nerves.

He whittled the stick to a sharp point with his hunting knife.

looked at different types of histograms to get the feel of different shapes of distributions.

A cubic curve with a horizontal cusp at the origin through four points

So where does this trend stop?

She pouted when she was told to wash the dishes.

Where are yer? said Mr. Thomas Marvel over his shoulder and coming on all fours.

So when you have dub, you have noise coming from the pulmonic and the aortic valve snapping shut.

And there were glowing arrows on the ceiling.

And then to generate the display you're about to see, all I did was touch it once per second on its nerve ring with a sharp pick that's sort of like the sharp tooth of a fish.

We're going to assume that some of our variables are normally distributed, we'll question that assumption but we'll assume it. And, we'll learn how to spot non normal distributions by looking at skew and kurtosis.

Then a knife maybe? Sometimes.

In the middle, you can see that little structure squeezing out, that's the left ventricle, pushing blood out through the aortic valve.

And of course that juxtaposition is of great interest to me because it creates a kind of a spark of new energy.

Eh! mother will be pleased when I tell her what th' skippin' rope's done for thee.

In El Greco's seventeenth century vision of Toledo, the cathedral forms an unshakable landmark beneath the stormy sky.

This is the dynamic sublime , as embodied in minute, but steadfast figures who stand firm against the elements.

So, we're at this cusp now of having a third replicator on our planet.

But the interesting thing about these computer virus infections was that, if you look at the rate at which the infection worked, they show this spiky behavior that you're used to from a flu virus.

We live across the street from a historic church that had lost its very iconic steeple in the storm.

Who could whisk away the thought of the one unlikely mouse padding along a cold water pipe behind the floral wallpaper, gripping a single wooden match between the needles of his teeth?

The ecliptic, which is the path of the sun, moon, and planets correspond to an offset circle.

Again, those two are giving you measures of variability.

Suspect will require a pencil sharpening tool to convert the writing stick into a weapon.

As the blood is now in the ventricles, you can see that the tricuspid and the mitral valve are open.

I'm sorry if I'm a bit edgy, but I'm usually not used to this cloak and dagger business.

The summary statistics that we'll focus on here are measures of central tendency, measures of variability, measures of skew, and measures of kurtosis.
