This is very unusual for caves.

Your paper on viral propagation was very insightful.

Type of study versus a true experimental design.

That's always possible when you're doing these types of studies.

And I think when you synthesize this research, you start with three key insights.

Disciplines.

Last segment we talked about the power of randomized experiments.

How low can you sink?

So you can think of this in those terms.

What kind of shit research are you doing?

How many masks do you need?

But they lack the power of randomized experiments, and I'd like to show you.

And they very helpfully tell you how to go and find the paper.

The brain is the record of the feelings of a life.

As a particle physicist, I study the elementary particles and how they interact on the most fundamental level.

Hi. Welcome to Statistics One. This is the first lecture where we'll talk about randomized experiments and observational studies.

Study in Pink ?

Until about a dozen years ago, when I was really captured by caves, and I really re focused most of my research in that direction.

So building community among those students, very important.

I worked on the environmental consequences of nuclear war.

The Laboratory

All of it? The research, the blogs.

So he was gay!

Imagine what the iPhone 8 will be able to do.

It gives a real insight into the child.

We couldn't get at the causal mechanism just by doing correlations and correlations and correlations.

The laboratory, Wilma.

Merrick Institute.

Crazy house.

Ectoplasmic research.

In the lab.

I'm doing research for an article...

Grades are an illusion.

I see enormous insight and potential.

An experiment is when we have random assignment conditions and something is minipulated in independent variable.

Einstein's especially interested in Penelope's talk.

I want to contrast that now. With, observational studies.

He was a senior fellow at the Bremming Institute for 12 years, then went off the grid.

The people from London came up.

We need to discover what those differences are.

He is a man of vision.

Here's an interesting one.

So, in order to get you in the mood as it were

We're now at about 2.8 seconds.

This is research can't buy it.
