If I tell you that somebody ranked their life eight on a scale of ten, you have a lot of uncertainty about how happy they are with their experiencing self.

And, again, I completely made up these data to look like this.

And how they can tell us a lot about what's going on in our data.

But just to be clear.

Is r larger than 0? r 0? Or r smaller than 0?

Correlation

TNEF Correlation Key

I am just gonna pause for a moment to let you think about that.

But there is zero correlation between IQ and emotional empathy, feeling with the other person.

The correlation is typically around 0.5 even 0.6 in some instances.

And, I'll show you the correlation matrix in a moment.

And looked at the correlations among their scores in those different disciplines.

So what you see here is a modest positive correlation.

There's a real correlation between a society that tells people that they can do anything, and the existence of low self esteem.

And the null hypothesis just says that there's no effect.

Though there's plenty who would.

So this can be applied to a correlational analysis.

Or here contributing to the numerator in the formula.

So I, I've sort of painted this picture here where I'm saying, well maybe extra virgin is positively correlated with happiness, but maybe that's only true at higher levels of

So the closer you get to positive one, the stronger you get the negative one, the stronger the correlation.

And here's the output from that script.

Which I haven't really explained yet.

It's quite possible that the other side got to him.

What I want you to do now is to see with your own eyes the relation between fall in child mortality and decrease in family size.

So, final slide, the important topics to take away is...

In MCMC, that's not true.

Throughout this whole thing, making toys,

It's larger than 0. If there's a positive relationship between x and y.

Treat their measurement with the thermometer as variable x2.

But I'm now coming upon ten years at Princeton, and it's sort of a different picture at Princeton.

This is, again, keep it simple, stupid.

Except now we're dealing with two variables, right?

If you think about this for a moment.

Unfortunately, it's not, because I would like to be taller, but I'm not.

The answer is yes clearly for different values of A, I get different values of B.

But the question I wanna pose to you. And I, I don't have a slide after this one.

In the middle of this distribution. What that means is if I did the study over, and over, and over again.

Well, it has to be at least 15.00.

What about causality?

So, the fact the reliability estimate is this high, I was, I was impressed.

So the important topics to take away from this segment.

It's very awkward to stab down into the chest of someone over half a foot taller.

The last question comes from Katembe.

There must be some single factor that caused.

They're all members of the same organization.
