**PsyDAG**, Saturday, October 24, 2009 at 10:48amSince we do not have the table, we can't help. You cannot copy and paste it on the site.

Use the formula for the difference between means.

This helps us to determine whether the difference between means is due solely to chance or if it is really a significant difference. The more unlikely it is to occur by chance, the more likely it is to be a significant difference. Most researchers use the criterion of P = .05 as a cutting point to make that decision. They say that since it is so unlikely to occur by chance, that it is significant. Although they might be wrong 5 times in 100, they are assuming that this is not one of these times.

By replicating the experiment and getting the same significant results repeatedly, this drastically reduces the probability of the results being due solely to chance.

I hope this helps. Thanks for asking.
