**PsyDAG**, Monday, August 31, 2009 at 10:20amThe first quartile defines the lowest 25%, while the third quartile defines the highest 25% (lowest 75%). With 13 scores arranged from lowest to highest, the 25% is between the 3rd and 4th scores and 75% between the 10th and 11th scores.

I hope this helps. Thanks for asking.
