If a construct is, is truly valid and has strong, a lot of support for it, then it will demonstrate all of these different types of validity.

That gives you content validity. So that's real easy.

That's happened quite a lot though.

So it's necessary to have both convergence, and divergence to establish, construct validity.

Now let's look at the different forms of validity.

And finally, up to 50 to 70 of software development effort is spent on validation and debugging.

Appropriate?

Does the test consist of words that children should know?

All right, let me copy and paste this one, too.

This test should be, correlated to a lesser degree with tests of spacial reasoning than it is, with a test of reading comprehension.

First we'll talk about reliability and validity in individual variables and individual, individual measures of psychological constructs, and then we'll talk about the idea of sampling.

normal, adequate, borderline, mildly.

What's fair?

valid

25, Patty.

The second form of validity, convergent validity, is where statistics and correlations come in.

It could simply be, motivation or the children's ability to take tests in general or, how happy they are in the school environment.

Is this proposition true? Is this theory a good theory?

So to recap this segment.

And how to interpret arguments based on cor relational analysis.

The Gorn's offer is reasonable.

Security guard's looking good.

The explored set, on the other hand, is easier.

So I will spend a lot of time in this course talking about things like reliability and validity that you don't typically see in an introductory Statistics textbook or in a first course.

He's the author of seven books, six of them on Mayan ceramics.

That meaning, it should converge with that other measure of that same construct.

That way we've shown some, convergent validity.

That's the inter item method and one of the most common ways we, we estimate reliability in psychology.

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.

Any doubts about the validity of this argument are promptly forgotten once we see the data.

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