Best ResponseYou've already chosen the best response.0\[(1.2)(1.3)(1.45) = 2.262\] so increase is 162.2%

Best ResponseYou've already chosen the best response.0if you want the geometric mean it will \[\sqrt[3]{1.2\times 1.3\times 1.45}\]

Best ResponseYou've already chosen the best response.0hey no this is an alternate formula of g.m in statistics is sigma logx/n

Best ResponseYou've already chosen the best response.0you want \[\frac{ln(1.2)+\ln(1.3)+\ln(1.45)}{3}\]?

anonymous

Best ResponseYou've already chosen the best response.0and what is d logic of using g.m here and not d mean?

Best ResponseYou've already chosen the best response.0How come you just can't do : (20 + 30 + 45)/3 = 31.6667% average increase?

anonymous

Best ResponseYou've already chosen the best response.0because this is the total after the increase. the increase itself is what comes after the one in the decimal

anonymous

Best ResponseYou've already chosen the best response.0for example if i want to increase a number by 30% i multiply it by 1.3

Best ResponseYou've already chosen the best response.0lol, I am in no position to help you. If Sat can't do it, I don't know who can. He's the smartest guy on here besides James. Now, that's someone you should probably consult.

Hero

Best ResponseYou've already chosen the best response.0He followed the formula you gave him. That's all that's required. I don't believe geometric mean applies to the formula.

Hero

Best ResponseYou've already chosen the best response.0You said it yourself, the formula is an alternative to the geometric mean formula.

Best ResponseYou've already chosen the best response.0What exactly is it about it that you don't understand? It's just a formula. You plug the numbers in and solve.
