COMPLETE Intro Psychology Course - ALL TOPICS - Internal Validity (Intro Psych Tutorial #20)

In this video I explain the concept of internal validity and how it acts as a checklist for considering whether an independent variable has been effectively manipulated, a dependent variable has been measured without bias, and a clear pattern can be found in the data. I also mention the importance of avoiding simple yes/no answers and remembering that all of these features are open to scrutiny, criticism, and debate. Finally, I underscore the importance of limiting conclusions to the data that has actually been collected. Don’t forget to subscribe to the channel to see future videos!
