chi-square: testing for goodness of fit
... Generally speaking, we should be pleased to find a sample value of χ2 /ν that is near 1, its mean value for a good fit. In the final analysis, we must be guided by our own intuition and judgment. The chi-square test, being of a statistical nature, serves only as an indicator, and cannot be iron clad ...
