AMC8 2010 8, Problem 4

What is the sum of the mean, median, and mode of the numbers $2,3,0,3,1,4,0,3$?

Solution: Putting the numbers in numerical order we get the list $0,0,1,2,3,3,3,4.$ The mode is $3.$ The median is $\frac{2+3}{2}=2.5.$ The average is $\frac{0+0+1+2+3+3+3+4}{8}=\frac{16}{8}=2.$ The sum of all three is $3+2.5+2=\fbox{7.5}$

Answer: 7.5
