Was about to say that. It’s sad that your comment is the very last in this thread.

guess the correlation, looks about like a solid 0.1. Whoever put that regression line in there is crazy, the confidence interval is insulting.

1: it’s not last, and 2: it’s not sad, because 3: people aren’t reading the source material. I love xkcd, too, but that doesn’t apply here.
We don’t need to throw satire pies in the just because results don’t match expectations doesn’t mean we should throw pies of satire in their face. This is actually interesting.

The data does not support the conclusion. A simple “no” is okay. Take a look at these examples of regression. See how any one of the conclusions is absurd? Mind you the data in that example is far less random!

How do you think a case of “this explains some of the differences in the population, but not a lot” should look?
And that looks potentially fine for an error bar. For a mean estimate, SE=SD/√N , so depending on what error band they used this looks quite plausible.

Also, the R^2 is even in the picture: .11

I recommend finding a different statistics teacher, preferably one who isn’t a comic and one who knows what the difference between a standard deviation, a standard error, and a 95% interval is. Those should not be too hard to find, it’s relatively basic stuff, but many people actually kinda struggle with the concepts (made harder by various factors, don’t get me started on the misuse of bar charts).

I post the picture because it gets the point across, not because that is “my teacher”. The point is that you can choose smart any random regression function and they all fit just as “good”.

No idea, sorry.
