   The formula for the mean of the sampling distribution of the difference between means is: μm1–m2 = μ1 – μ2. For example, let’s say the mean score on a depression test for a group of 100 middle-aged men is 35 and for 100 middle-aged women it is 25. If you took a large number of samples from both these groups and calculated the mean ...

   Does a mean difference tell you a lot?

   • On its own, the mean difference doesn’t tell you a lot (other than give you a number for the difference). The number may be statistically significant, or it could just be due to random variations or chance. In order to test the hypothesis that your results could be significant, run a hypothesis test for differences between means.
