Statistics: Median
Rita went on vacation thrice in 2005, four times in 2004, twice in each of the years 2002 and 2003, and once in 2006. What is the sum of the median, mode, and range of her annual number of vacation trips from 2002 to 2006, inclusive?
Correct.

List down Rita's trips as a list of numbers:
>$$\{1, 2, 2, 3, 4\}$$.
The number 2 appears most often, so it is the mode.
The middle value is also 2, so the median is 2.
The range is $$4 - 1 = 3$$.
Hence, the sum of all three is $$2 + 2 + 3 = 7$$.
