The sum of the 10 numbers is 56. The mean is 56/10 = 5.6. The most common number is 3, which is the mode. Since there is an even number (10) of numbers in the list, the median is the average of the 5th and 6th numbers when the list is arranged in an ascending order. The median is therefore equal to (4 + 5)/2 = 4.5.
