What does NHST tell us when a "statistically significant" finding is obtained?
We know that something interesting has happened. We have obtained evidence for the fact that there is a nonzero difference between the population means and it is likely in the direction we observed with the group means in an experiment. We also know that the smaller the exact probability, the greater is the probability that an exact replication will produce a statistically significant (p < .05) finding.
