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?

[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.

[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 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.

thank you

[sgtbetts]

Oh wow. Huh. I actually get this. I can't thank you enough. You > my textbook.

[smith22969]

shit, man, where were you when i took stats?

[mustbeteaching]

Thank you....my online statistics class is failing to explain this in any real sense.

[yank619]

great explaination.....prof ....thank you

[grecianinferno]

Thank you for the video. Does the formula for chi-squared have any relation to finding the percent discrepancy of an experimental and actual value, or is this coincidence? Thanks again!

[Xpalman]

just wanted to say thanks. I just received my statistics result and i did pass it (with some sort of miracle) and all thanks to youtube videos and one of them which helped me understand it was yours.

Thanks again.

Useful lecture, thank you

[kind03cn]

悲剧，我什么都听不懂！

[kind03cn]

Due to my poor English listening skill, i can't recognize what the professor at all! Tragedy!! 悲剧！

[spand3244]

Thanks!

But i find it a little frustrated and quite disturbing.

You see, there is only five stars for a maximum level, but i wanted to give atleast 10!

Now how do i solve this? mark 5 two times?

well... you own it.

Keep going. And feel free to enlight us more!

[OhAhm3d]

Thanks

[Alterstateresearcher]

You sir are a very effective communicator, I was in sore need of a proper explaination for this method in my biostatistcs course.

[dchokee]

good stuff. thanks.

[trisky1234]

Thanks! you just saved my butt in statistics class

[TheBigHostizzle]

This really really helped me with my phase test. Thank you very much.

[pima04]

good, i learned something.
