OK, people, this is basic stuff they teach in high school freshman pre-algebra. Ronin apparently remembers his high school education. Mean, or in layman's terms, average, is the sum of a list of numbers, divided by the number of entries in the list. This is usually close to 50% on a histogram, but not always. Median is the middle value of a list. If the list of numbers has an even number of entries, the median is equal to the sum of the two middle numbers divided by two (after sorting). If the list has an odd number of entries, it's the number in the middle (once again, after sorting). This is your 50% mark on a histogram. Mode is the most frequent value seen on the list. A list of numbers may have no mode, or more than one mode. -- .''`.
