Why do we reject the null hypothesis in Goodness of fit when the Chi square statistic is less than the tabulated value of chi-square at say 5% level of significance and accept when it is more?(adsbygoogle = window.adsbygoogle || []).push({});

What does it mean to have a Chi-square valuemoreorlessthan the value assigned to a certain level of significance?

Edited: The homogeneity thing was wrong, so I removed it.
