### Interpret Chi Squared

Posted:

**Sun Mar 19, 2017 10:10 am**Hi all,

So I seem to have a very 'high' Chi² value of 357.47 and I am struggling to interpret this. As per the SmartPLS Documentation, Chi² value is calculated using the following formula (N-1)*L (N is the number of observations and L is the maximum likelihood function). I know that Chi² is used to test the significance of my findings and see if this matches whether the distribution of values in a statistical sample conforms to a known theoretical distribution.

I have 184 respondents and I know that degrees of freedom is used in the calculation however I do not know how to interpret the value. If I don't know the df then how will I know what p value is associated to the Chi² value and know if the value 357.47 means I can reject the null hypothesis? I was under the impression that a low Chi value means that the null hypothese can be rejected. Can 357.47 be converted to a percentage?

Is anyone able to shed more light on this?

Thanks!
