+4 The mode of a set of numbers is the number that appears most often in the set. The mean is the average of the numbers. The median is the middle number after they've been put in order (or the average of the two middle numbers if there are two numbers in the middle.) Find the sum of the mean, median and mode for this data:
86 72 16 42 16 55 16 12 91 55
+312 Its not that hard... If you know what the Median, mode and Average is, you should know this. The average is the sum divided by the number of elements in the set.
