confucius principle of mean

I will assume 'confucius' is in reality 'confusion' and you aren't referring to the Chinese philosopher.

The mean, or more properly the arithmetic mean, it the sum of a list of entries (numbers) divided by the number of entries.

If I wanted the arithmetic mean of

11
14
8
6
4

I'd add the entries (11+14+8+6+4=43) and divide that sum by number of entries (5) for an arithmetic mean of 8.5
