test statistic > critical value

Tests if category labels in a 2-way classification table have some meaningful relationship to counts

'= X - 1 - number of estimated distribution parameters

p value increases

test statistic increases

'= (X-1)(Y-1)

Tests if specified distribution of H0 matches a sample

Tests if multiple unspecified probability distributions are the same

1.	Goodness of fit
2.	Independence
3.	Homogeneity
4.	DF for a two-way contingency table of X rows and Y columns
5.	DF for a goodness of fit with X cells
6.	As the difference between observed and expected counts increases
7.	As the test statistic decreases
8.	H0 is rejected
