The simple correlation coefficient is about 0.9!

Correlation

Coefficient.

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

Real coefficient

Imaginary coefficient

leading coefficient.

And notice this coefficient is the same as that coefficient.

TNEF Correlation Key

The leading coefficient of the first row is 1 2 is the leading coefficient of the second row 4 is the leading coefficient of the third row, and the last row does not have a leading coefficient.

By the inverse of the coefficient.

3 The Gini coefficient (coefficient of income concentration) makes it possible to numerically assess the degree of inequality.

China s coefficient is 0.47.

Target values Gini coefficient

That's the fifth coefficient.

What's the sixth coefficient?

This coefficient becomes 4.

The coefficient is 1.

So what's 1 2 of this coefficient?

So the coefficient of friction tells us

And remember coefficient of friction are unitless

In the next few videos, we'll use coefficient of friction or calculate coefficient of friction to do some more problems

So the correlation is low.

It's an extraordinarily close correlation.

These are the same surfaces is why should the coefficient of friction here why should the coefficient of static friction so this is here, this is stationary what's under place of coefficient of static friction why should that be larger than the coefficient of kinetic friction over here?

You literally just look at this coefficient right here, and you say, OK, well what's half of that coefficient?

If we can't get a 1 coefficient, we'll at least have a lower coefficient here.

Times its coefficient times the fifth term's coefficient divided by 5, for the fifth term.

I'll do a video on why sometimes a coefficient of static friction can be different than the coefficient of kinetic friction

So we can say this generally coefficient of kinetic friction is less than or equal to the coefficient of static friction

The first coefficient is 1.

So, the coefficient is 1.

The coefficient here is 1.

We determined the undetermined coefficient.

The coefficient here is 11.

The coefficient there is 1.

The coefficient there is 2.

Well, half of that coefficient is negative 2.

We call this the coefficient of static friction

And the interesting thing here is that the coefficient the way I've set up this problem the coefficient of kinetic friction is lower, if we assume the same materials than the coefficient of static friction

For this, mere correlation is sufficient.

Correlation in itself doesn't prove causality.

4A plus C, the coefficient of the s terms.

Plus B, some undetermined coefficient times cosine of x.
