The arithmetic mean (AKA average) of n numbers is the sum of those numbers divided by n. For example, the arithmetic mean of 45 and 55 (note that n = 2) is (45 + 55) / 2 = 50. The arithmetic mean of 1, 2 and 3 (here n = 3) is (1 + 2 + 3) / 3 = 2.<br /><br />The geometric mean is similar, except that instead of adding the n numbers you multiply them. And instead of dividing by n, you take the nth root. In the case above, the geometric mean is the square root of 66 × 99.<br /><br />33 × the square root of 6 is another way of expressing that. Amy pulled out the perfect square factors from the product, and was left with a 6 in the radical.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-5314424421029333860.post-63081337525670408612012-12-26T19:44:59.283-08:002012-12-26T19:44:59.283-08:00Okay...I went out and did some searching for what ...Okay...I went out and did some searching for what the heck a geometric mean is, and am still confuses. :( I need some 'splaynin'. I guess I like the air quotes best. :)Don Naffnoreply@blogger.com
