You read a report disseminated among your HR team that includes statistical test results on the effects of a new training program. The employees who received training reported much fewer mistakes on the job, compared to employees who did not receive any training, t (110) = 4.41, p < .001). A friend leans over and says, "What does p less than .001 mean?" How do you respond? It means the chances of the trained employees doing so much better was less than .001 percent It means the chances of finding a t statistic of that size, if training had no effect, are less than .001 It means there's a less than .001 chance that the results were due to chance It means there's a .001 chance that the two groups actually made the same amount of mistakes, and we just missed it
