**PsyDAG**, Tuesday, June 30, 2009 at 11:10amI assume you can calculate the means and standard deviations.

In explaining the difference between means, you might mention the null hypothesis and alternate hypothesis (two-tailed or one-tailed), along with the probability of alpha (type I) error (rejecting null hypothesis when it is really true).

Whether you accept or reject the null hypothesis, then you need to interpret the meaning of your results.

Of course, you will need to elaborate this information. You will find that, if you can explain the process clearly to someone else, you will have a much clearer understanding of the process yourself. It makes your knowledge much more explicit. Good luck!

I hope this helps. Thanks for asking.
