What is the mean of a set of numbers?

Mean is a measure of central tendency.  It is the average of a set of numbers. It is determined by adding the numbers together and dividing them by the total number.

Mean = sum of the numbers / total number

Mean number of fatalities in 2010 = (2290 + 2016 + 2423 + 2777+ 2934 + 2795 + 3095 + 2083 + 3024 + 3056 + 2795 + 2597) / 12 = 2740.42

Mean number of fatalities in 2011 = (2365 + 2912 + 3011 + 2638 + 2459 + 2154 + 2268 + 2750 + 2545 + 2323 + 2741 + 2912) / 12 = 2589.83
