Randomized Control Trials and Confounding

In this video, Dr Greg Martin describes how randomized control trials work and how they deal with confounding variables. This is episode three in a series of videos looking at epidemiology, research methods and study design in the context of global health.

Global health (and public health) is truly multidisciplinary and leans on epidemiology, health economics, health policy, statistics, ethics, demography.... the list goes on and on. This YouTube channel is here to provide you with some teaching and information on these topics. I've also posted some videos on how to find work in the global health space and how to raise money or get a grant for your projects.

Please feel free to leave comments and questions - I'll respond to all of them (we'll, I'll try to at least). Feel free to make suggestions as to future content for the channel.

Excellent explanation. Background music is very distracting.

I have a research methodology exam tomorrow and you've given me the confidence I never thought I'd have, thank you so much

[darkapexx]

Thank you, you are much better than my professor at school. Saving me for my Research Methods Final! Keep it up.

I have been struggling to understand confounding but this 4-minute video has helped me understand it so well! Thank you for this!

[otahmedabad]

thank you so much for explaining it in short. really like your video on research as it explains perfectly without taking so much time. keep it up.

Excellent explanation of confounding factor.. U mean that confounding factor is associated with risk factor and outcome but not related to causation of the outcome. It remains same in both groups. It doesn't change.

Hallo Greg, am a mid career epidemiologist starting an online MPH soon and the short to the point character of your videos is an excellent refresher on key topics. Bravo!

If the music was just slightly lower, it would be even better. Liked and subscribed!
