Mean is the average number in a set of data. To calculate mean, you add up all the numbers in a set of data and divide that sum by the amount of numbers you just added up. Example: numbers: 2, 2, 1, 3. 2+2+1+3=8.
You wear your wedding ring on the left hand, the finger next to your pinky finger. It is usually the third finger of the left hand, but there's no rule saying that it has to be that finger. In some parts of the world people wear it on their right hands, and in other parts of the world wedding rings are not worn at all.
Ring Finger of the Left Hand . A promise ring is a promise of commitment and often precedes an engagement. Therefore many couples like to wear a promise ring on what is traditionally thought of as being the wedding ring finger -- the ring finger of the left hand. When engagement rings have been exchanged, the promise ring is then worn on another finger. Tip: Remember that every finger is a different size. The ring finger of a left hand may well be a different size to the ring finger of the right hand. Therefore if a promise ring is going to be an expensive purchase, it is worth considering whether the size of the ring can be altered if it will be worn differently in the future.
