I'm not any kind of mathematician. I've only ever seen p values around 0.001 or suchlike, never zero before. As I understand it, the p value (probability value) is the likelihood that the finding under discussion could have occurred by random chance, so a p value of zero means it absolutely under no circumstances could have occurred by chance. I hope that's correct.

It's zero due to rounding. You could never get a value of absolute zero unless your data was fake.
It's not letting me 'like', but that's helpful. Thanks. I was puzzled by the p = 0 Explaining that it's due to rounding makes that clearer.
