  The best thing is to give students lots of example, rather than adhere to
the definitions.  The Connected Mathematics Project has some wonderful
exercises that do activities for middle school children on this very topic.
One activity has the students write down the number of letters on one post-it
note and then write the letters in their first name, one letter per post it
on others.  Students then post their total numbers and their names on a
wall. Or the board in the classroom.  

egin a discussion of what the mean would be....is someone's name located at 
the mean....if the mean turns out to be not a whole number value is a good 
measurement to represent letters in someone's first name?  Do the median?  
Is there a mode, two modes...? The student's personalize the info and it 
makes for a very interesting class and one they will remember.  The CMP goes 
on to list facts about longest names, most common last names, etc.
