@CogitoErgoCogitoSum Maybe come at it again. I'm not trivializing your comment or attempting to ' blow it off'.

I'm unaware of your background and was not in any referring to it. another framing of your question wouldbe interesting.

[CogitoErgoCogitoSum]

@Lisnageeragh Its been so long since I wrote that, I sort of forgot what I was talking about. But you certainly dont get what I was talking about either. You sort of trivialized my comment and blew it off. I'll have you know Im not your typical wetodd. Im just new to statistics, thats all. You arent getting my question, and for reasons that are probably my fault.

[Lisnageeragh]

@CogitoErgoCogitoSum The 'normal distribution' has its own unique set of parameters and ,in fact defines what we are looking for in the first place. Given this exposition , I can see where you are coming from.

i thought Chi-Squared was a inferential statistic?

[CogitoErgoCogitoSum]

How do you generate a normal distribution in the first place for the purpose of matching it with your data? Is finding the mean and standard deviation of your data sufficient for creating an *appropriate* normal curve? I mean to say that if you were to adjust your mean and standard deviation, from what your data suggests, you may be able to optimize, so to speak, and create a more accurate normal with a lower chi-square value. Is this what we do? Is it even rational to do?
