So I found the mean that was 600 then i did the step where u subtract the numbers by 600 and then I squared the dif and added the numbers and got 1500314 what do i do with this number?

Best ResponseYou've already chosen the best response.0Im trying to find the standard deviation and i just need to kno the last step. I found the mean and i subtracted the mean from the numbers then i squared teh difference and added the numbers and got 1500314 now i need to kno wat to do its like n1=?=? idk what the last step is....

Best ResponseYou've already chosen the best response.1id suggest working with a "smaller" set .... subtract 100 from all of it

Best ResponseYou've already chosen the best response.1itll retain the same standard deviation

Best ResponseYou've already chosen the best response.1im saying; make life easier on yourself .... subtract 100 from all the numbers; if your mean is 600, then your modified mean will be 6 2, 2, 3, 14, 1, 10

Best ResponseYou've already chosen the best response.1in fact, this is a good way to find the mean .... since its just going to be 100 more than the smaller set ... im sure im speaking english :/ 102 98 103 86 101 110 100 100 100 100 100 100  2 2 3 14 1 10

Best ResponseYou've already chosen the best response.122+314+1+10 = 0 ... that was sweet your original mean should been 100 ....

Best ResponseYou've already chosen the best response.0no the book told me how to do it... dude please just tell me the last step. its like n1= something wat is that last step?

Best ResponseYou've already chosen the best response.1since the mean of this smaller set is 0, all we need to do is subtract 0 from each value ... and square 2^2 = 4 2^2 = 4 3^2 = 9 14^2 = 196 1^2 = 1 10^2 = 100  add: = 314 your set is assumed to be a population, unless it was stated otherwise elsewhere, so divide by n = 6 314/6 = 52.3333 ; sqrt that for the std deviation sqrt(52.3333) = 7.3422

Best ResponseYou've already chosen the best response.1the numbers YOU found are waaayyyyy off; since the mean is not 600 ....

Best ResponseYou've already chosen the best response.1I know what she did....she just added the numbers together....you then need to divide by the total numbers (600/6 = 100). The mean is 100.
