i understand the problem and thank you for your help.... i talked to my professor about the formulas the example give you, and they are totally skewed. She said if you got the standard deviation and mean correct it was ok. I also see now why you should use the 3/2.0 since 3/2 will give you one. One question, what is the std:: for? another way to use the c standard lib? also you reinitialized the "i" variable in both loops. plus there were two other errors, saying the pow and sqrt functions not part of the std library... I think because they are in the math library.
