Measurement and Validity (The Effect, Videos on Causality, Ep 67)

The Effect is a book about research design and causal inference. How can we use data to learn about the world? How can we answer questions about whether X causes Y even if we can't run a randomized experiment? The book covers these things and plenty more. These videos are meant to accompany the book, although they can also be viewed on their own.

This video relates to material found in Chapter 22 of the book.

After following all the other chapters in this book, you thought you were in the clear? Ha! There are plenty of other things that can go wrong. In this video I cover some ways in which the data... might not even be the data. Measurement error and validity are specters over any empirical research project.
