That's not what a p-value is. A p-value is the probability of getting by random chance a result at least as extreme as the measurement. This is not the same as the probability that the effect you measured is due to chance. The latter isn't even well defined without additional assumptions.
- FrankyHollywood 11y agoCould you please explain what you mean, what is the difference you talk about? Roll a dice 100 times, and on average 5 rolls have the pattern I want. v.s. I have found pattern and there is a 5% change it was due to random. Is that not the same?
- rspeer 11y agoThe things you're asking to compare aren't particularly clear, but I'm fairly certain they're not the same. The English phrase "due to" describes a causal connection between events, and p-values don't.
