Moderator Two minutes.

So... Moderator That's it.

Moderator Yes, I am sure.

And Z for the moderator variable.

Then we add in a moderator variable.

Moderator Eva, we have about five minutes.

If a moderator variable is introduced, that is, and it's a strong moderator, what that means is B1 isn't representative for all values of X.

So the moderator, you can think of it as sort of controlling or influential.

So today we're gonna focus on the moderator variable.

Moderator Tell me when your last trip to Russia was.

Now let's introduce a moderator variable, a sort of Debbie Downer in this example laugh .

So the moderator has influence or control over another ah, relationship.

Now we have Professor Thrun here with me I'm Andy the moderator in the CS373 forum.

So we're just gonna look at extroversion happiness and a moderator, so let's add in socioeconomic status.

But again, the concept here of moderation is a moderator variable and I'm just using the letter Z to, instead of X, to distinguish it.

So, a moderator can just sort of immediately impact one person, ah, in this distribution of people, same thing with ah, with statistically and relationships among variables.

Well, we have to add in a moderator variable and a, what I'm going to call a product term.

So, if we have say'X' and 'Y', and say these are co related, the moderator can just zap that.

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

Ah what we'll do in the next lecture, we won't touch this variable today, is we'll, we'll consider a moderator variable on that relationship.

And when I realized that Tim Russert, former moderator of Meet the Press, was talking about my writing, while I was living in a van in a Wal Mart parking lot,

Moderator can say nope it's not correlated under my roof. Or he can say hey I'm gonna enhance that correlation, I think it's really important.

It has sway, it has influence over the relationship between X and Y. So again, suppose X and Y are positively correlated, we introduce the moderator and zap, it could just eliminate that correlation or zing, it could make it stronger.

Traps are of many kinds of wood, of steel, of words.

But vulnerability is also the birthplace of joy, of love, of belonging, of creativity, of faith.

They die of HlV, they die of hepatitis C, they die of infections of their heart valves, they die of infections of their brains, of their spines, of their hearts, of their bloodstream.
