thank you for the video, it is interesting! I have a question please, how could you write so perfectly, how did you make the video with this kind of pen ?
In any study group there are going to be healthier participants (i.e. no co-morbidities) and unhealthy (aka sicker) patients. If these are not distributed equally between the two study groups, you will likely see significant bias in your results in favour of which ever group has the healthier participants. It's for that reason that randomization is so important.
Very useful knowledge, the explanation is clear. Thanks a lot!
You deserve much more views .... great videos
are there specific names for the bias you mentioned in each example?

I use software called VideoScribe from Sparkol. www.sparkol.com/
Who’s definition of bias did you use?
and why the heck would you treat healthy people ? shouldn't both of the group be sick ?
