Controversy
If A caused B then there is a correlation between A and B.
The rising of the Sun caused the eating of an ice cream by John.
Therefore, there is a correlation between the rising of the Sun and the eating of an ice cream by John.
My question is, how would you quantify those events and plot the correlation between them on a graph? Would I count the number of times these events occurred? What if an event only causes another once? What if John died after the first ice cream? Can we still say that there was a correlation?

Wait. Technically everything is connected. Maybe the relationship between 2 variables are correlated even tho it doesn't make sense that they cause each other, but that happens because these 2 variables are connected to other variables that we didn't observe yet these variables can indirectly influence the relationship between the main 2 variables we are comparing. So I guess that means, one way or another, correlation DOES imply causation. Error 404

Is anyone else surprised about that slope for heights of dads v. heights of sons? 0. 5? Isn't that weird? At what age were the sons measured? Surely, height of dad v. height of son should look a little like 1: 1 -- otherwise would people not be shorter and shorter?

over all a good video but at 4: 59 it is not proven that vaccines lower illnesses. it is a common misconpcetion, vaccinated people get sick just as often as unvaccinated. plus there is the added risk of harmful side-effects from vaccines so it might be even worse

-crash course team, not all the graphs in the datasaurus dozen shown in the end doesn't seems like having same correlation coefficient. Few look like having r=1, few r=0. Please correct me if I'm wrong

Squared correlation r-2
Line of regression
Can anyone explain a little more in depth standard deviation? Im still not sure what information it tells us in a scatter plot

I watched this video without having seen the previous ones, and spent a considerable amount of time wondering -what the heck is an 'old faithful eruption'? -

Just because the UK joined the EU, it doesn't mean the EU was responsible for improving the economy in the UK. Correlation is not causation.
