We haven't a clue about which stats book you're using. Plus -- most of us don't have multiple stats book here at home. With 41 numbers, 12.3 is the top of the 30th percentile.

The central tendency is the measure that best describes the data. The mean doesn't, because 5 is so much different than the other data. That leaves you median or mode. Check this site and decide which one fits this data. http://www.quickmba.com/stats/centralten/
