Distribution Analysis Tool : Chi square significance guide info

Manojkumar
8 - Asteroid

 Hi, 

 

When i ran a sample normally distributed data in 'Distribution Analysis tool' i got the following results. The significance is coming out as 0 (p=0) which <0.05 so the inference is data is normally distributed as expected. But the guidelines below says chi-sq significance has to be greater than 0.05. I am a bit confused about this guideline. Can someone please explain the reason for such guideline in distribution analysis tool?

 

Thanks in advance

@Manojkumar could you rerun the Distribution Analysis tool with all the Distributions selected for your data.  This will then give you all of the statistical outputs for Chi-Squared.  From your screenshot, I believe you only have Normal selected.

Hi ,

 

Thanks for response, but what you pointed out is only different distirbutions. Anyway i have run with all selected as you suggested and sharing the results below. As you see all the distributions under Chi-Square test says significance as "0" and guideline says it has to be >0.05 to be considered a good fit. Please correct me if i am wrong.
