3.8 Matching | Quantitative methods | Research Designs | UvA

This video introduces the concept of matching participants. Sometimes random assignment is impossible, which increases the selection threat to internal validity. One way to mitigate this threat is to match participants on relevant background variables. You also learn about undermatching and regression to the mean.

Thank you! This is a great summary of what matching is. I feel more ready to tackle textbook explanations now.

It isn’t really. This is really about regression to the mean and very little about matching.
