And this path through the mediator, From x to the mediator,

The invention is accredited to Edison.

He is accredited with the invention.

He was accredited with these words.

The mediator is from Pune, India.

I need to be an accredited press person.

The invention of electric light is accredited to Edison.

He was accredited to the United States to represent Japan.

You know, my science teacher was not an accredited teacher.

Like a summer camp? No, we're an accredited high school.

A good mediator can make a deal go smoothly.

I am saying we can predict Y from the mediator.

And this 0.22 was 0.28 before adding in the mediator.

How nice. As a mediator, or to stop the bleeding?

Right? Uh, then you wanna make sure that the mediator and

She, it turns out, has a non accredited correspondence course Ph.D. from somewhere in America.

So, as we go from x to the mediator to y, If those events happen over time so that the mediator follows x and the outcome follows the mediator, then again, we're moving towards scenarios where we can make stronger claims or stronger arguments of that causality.

One, just think about what the word mediation or a mediator uh, means.

But X might remain significant even in the face of a significant mediator.

Big concert halls, they require me to be an accredited photographer working for a music magazine.

Now, let's add a mediator. This is still in the world of path analysis.

Because the mediator will explain all the variance in Y that X was accounting for.

From the mediator to y, That's known as the indirect effect on our outcome variable y.

They are tested and accredited according to International Mine Action Standards, just like dogs have to pass a test.

So, what this image depicts is here in the middle uh, a person who is a mediator.

Is we can predict the mediator from X. But to include this entire, sort of path diagram.

Uh, but for now, we'll just keep them as predictor and outcome. I'll use M for the mediator.

Now if we add an in a mediator variable, we will actually wind up with three regression equations here.

Of, our outcome and it significantly predicts the mediator. Now let's look at the full model, that's down here.

If the animal does that, it gets a license as an accredited animal to be operational in the field just like dogs, by the way.

So the question is, what happens to the predictive validity or the, the predictive value of X after you add in the mediator.

The evidence for that is that, that direct effect did not go completely away it was still significant after we added the mediator.

I am just going to show you two. So we have, our first one is uh, we can predict why from the mediator variable.

So what's a, what's a possible mediator or mechanism of that. Now, I, I just made this up and I just made up the data.

And secondly we can predict the mediate, mediator variable from X. So the first regression equation, what I'm doing is just picking off this piece.

Both predictors into one regression equation, so here's the full model, so to speak, as it has both the mediator and the, uh original predictor.

If, if X and Y are correlated because of the mediator, as I've said here on the slide. Then. X should no longer be significant.

So, x, y, m our predictor outcome, our mediator they will all be represented by rectangles because we observe them, they are scores on a survey.

And if we can find a mediator variable that accounts for the same variance in y, then we're one step closer to understanding the mechanism, that links x and y.

So now, we have y and we have two sources of variance, two sources of systematic variance for a y We have x, the direct effect, but we also have the mediator.

God is He that created the heavens and the earth, and what between them is, in six days, then seated Himself upon the Throne. Apart from Him, you have no protector neither mediator will you not remember?

So, that predictor variable, instead of just being something like extraversion, I could manipulate something and then, my outcome variable could be a true dependent variable, and we could look for a mediator of that experimental effect.

Allah it is Who created the heavens and the earth, and that which is between them, in six Days. Then He mounted the Throne. Ye have not, beside Him, a protecting friend or mediator. Will ye not then remember?

And when My slaves ask you (O Muhammad SAW) concerning Me, then (answer them), I am indeed near (to them by My Knowledge). I respond to the invocations of the supplicant when he calls on Me (without any mediator or intercessor). So let them obey Me and believe in Me, so that they may be led aright.
