Here we expect a positive correlation.

So the correlation is a positive.22.

Slight high correlation, or puh, puh, sorry, positive correlation for high SES.

Correlations can range from positive one, which is a perfect positive correlation.

I don't see that strong positive correlation at Princeton.

What do you need for a strong, positive correlation?

So what you see here is a modest positive correlation.

That's different from the last lecture where we saw a positive correlation.

So, this is a strong positive correlation between working memory capacity and, and

Correlation

Is there any correlation, positive or negative, between intelligence and tendency to be religious?

So, how do we untangle that positive correlation in trying to predict the outcome measure?

And what you see is a nice positive correlation between runs and batting average.4.

And it's standardized so that the correlation coefficient falls between positive one and negative one.

So I've said that the alternative is that the correlation is greater than zero, or positive.

Okay, so. A correlation, this simply defining correlation.

TNEF Correlation Key

That's called correlation.

We saw a nice correlation, positive correlation of .40 what I've done now with this plot is I've put the actual player names next to each individual dot.

And what we see is a nice moderate to strong positive correlation between working memory capacity and SAT.

And, then, the alternative hypothesis is that, there's a positive correlation, say, between, say, working memory capacity, and

Here are three data sets in one, we have a strongly positive correlation in another, it's above zero, and in the third one, it will be a negative correlation.

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

Specifically the correlation analysis.

So you might observe a positive correlation between x and y, introduce a moderator and boom it could go away.

Remember from the lecture on correlation, then, that represents the covariance or correlation.

Positive seven times positive three.

What positive? Positive what? Pressure.

So the correlation is low.

It's an extraordinarily close correlation.

We could observe a correlation.

Just to give you a sense of the correlation, the correlation is about .5.

So you would think that the more years out, the higher their salary, so there's probably a positive correlation between those two.

Our plan now is we compute the Phi correlation for each line, and then we rank the lines from high correlation to low correlation.

But we'll look at the correlation analysis and you'll see that that's the correlation coefficient.

Correlation in itself doesn't prove causality.
