Shouldn't be the probability of the error alpha instead of p for the alpha error? The argument is that one sets a statistical procedure to have a certain probability of failing to not reject a null hypothesis (one controls that probability). The p-value is just a random variable used in the same way than the test statistic: if p is below alpha, then I reject the null hypothesis (and thus, if that hypothesis is true, I'd just be wrong alpha% of the time). What you think about this reasoning? Great blog btw. Cheers from Chile!

I think that putting statical concepts into words can be misleading if people read the same thing in two different ways. I have YouTube videos on p and and on Alpha, as well as how they work together. I'd suggest taking a look at them. For links, see the "Videos" page of this website.
