But what she was doing was actually making a model of a mathematical structure, that many mathematicians had thought it was actually impossible to model.

Welcome back for Unit 3.

And there are a number of ways to assess construct validity.

It's an idea. Greatness.

We've certainly used logic all over the place in this class.

The Founding Fathers were, for my point of view, the original anatomical activists, and this is why.

So to demonstrate this, let's think about the construct, verbal ability, in children.

In psychology and social sciences, this is a, a major emphasis of research.

Then we haven't established that it is valid but now we are moving towards, we're able to see if we have valid construct.

I can observe a person performing an intelligence test, but I can't just look at them and observe their intelligence.

I have used tools like the lexer and parser generators we're learning about in this class, Programming Languages.

Tell the truth!

Structures

Now you might say, hey Sal, why are you even introducing this idea of a linear combination?

Because it's an ideal. It's an imaginary thing. We can't have it.

(Laughter)

One, the numbers you'll never get to see.

Well, John, that that's all relative.

We'll walk through that. That's how we get estimates of reliability.

Generally speaking is measurement, but I'll break this lecture up into two segments.

This is a difficult question, particularly in the social sciences.

Let's break stereotypes!

I'm not super familiar with scrypt. It seems like the same concept but a little bit better.

They are over 2,000 years old.

As well as, divergent validity. If we only show, convergent validity then we can't be really sure.

It adds more transforms into the list that you can then use. We now have some six transforms that we can set in this system.

So that is authoritarianism.

Okay?

The first thing we want to do, is what's called procedural abstraction.

And finally, human resources

'cause they can shoot around here too and then we all fucked.

Death is a primitive concept.

And suggest concepts to Fischer's conscious mind.
