WebbEvery run of an experiment has random noise; the p value is basically the probability that the means were different only because of these random factors. Thus, if the p value is less than 0.05, then we have a 95% confidence that there really is a difference. (There's a more precise meaning for this, which we'll get to in a bit.)
