List a set of 11 numbers whose mean, median and mode are the same 

Example 1:

A trivial example - all entries are the same

5,5,5,5,5,5,5,5,5,5,5

• "5" is most common - it is the mode
• "5" is the average of the set - it is the mean
• Half the numbers are above "5" and half below - it is the median

5 is the mean, median and mode (all three distinctions)

Example 2:

1,2,3,4,5,5,5,6,7,8,9
