Download Lecture Overview
00:01 What have you learned from this lecture? Well you now know the definition of an experiment, if you recall, an experiment is when you, the investigator manipulates a variable in the study. You now know the purpose of blinding and randomization. Randomization is about controlling for extraneous variables that, as a result, improve our internal validity. You now know the characteristics of the different kinds of experiments, the RCT, randomized controlled trial, the quasi-experimental design and the natural experiment, as well as this thing that I've called the ecological study, which isn't strictly an experiment, but we tend to talk about it with experiments. And you also understand the nature of Hawthorne and Rosenthal effects, which are kinds of biases we encounter a lot in RCTs and which are the reason that we prefer blinded studies. 00:47 Thank you.
