These animations are largely made using manim, a scrappy open-source python library: https://github.com/3b1b/manim

If you want to check it out, I feel compelled to warn you that it's not the most well-documented tool, and it has many other quirks you might expect in a library someone wrote with only their own use in mind.

I really appreciate those who do this, as it helps make the lessons accessible to more people.

George ReynoldsYou might think that this is just some mathematical issue, but the point made at 1:52 can have dramatic consequences. An English solicitor Sally Clark was convicted of killing her two baby sons on this same statistical error given as "evidence" by an eminent doctor (not statistician) and jailed. She served three years of a longer sentence before the Royal College of Statisticians intervened to point out the error of multiplying the probability of two children dying of the same cause, which was sudden infant death syndrome, and more likely to be genetic and in both children. Her career destroyed, she died from alcohol intoxication (suicide?) and the "eminent" doctor was struck off the medical registration list.

k0p1k4ok so in short: simple multiplication of the probabilities is just a special case of Bayes’ theorem, when we have independence between events. therefore: P(A)=P(A|B).

1 month ago | [YT] | 22StaticiHopefully just a bit of constructive feedback: The bit at the start moving bars around representing where A and B are in terms of their probability is...not exactly intuitive. I'm still not entirely sure what the goal was with it; was an overlap intended to be shown? If so, well, it's just hard to see an overlap in that type of diagram.

1 month ago | [YT] | 162Good video nonetheless though! Thanks for it and especially the main one.

Lightn0xWhen I was first presented with this theorem, this is exactly the first thing I thought of. I thought "It's so obvious, how is this even helpful?". It was only later when I saw its many applications that I inderstood that a formula doesn't need to be complicated in order to be useful.

1 month ago | [YT] | 3michael antounIn the example given at 2:21, I noticed that the animation shows an increase in probability only horizontally, i.e. that your brother dying of heart disease means you are more likely to die of heart disease. Does it not also hold that if you die, of heart disease, your brother is then more likely to die of heart disease, implying a stretch not only horizontally but also vertically? If my thinking is incorrect, I'm very interested as to why.
