validate the normal probability distribution assumption?

probability distribution describes the distribution of counts

levels of a variable. A special case is the binomial discrete

distribution. For each level of a variable, which is common to

populations, equality of distributions can be tested.

1. ANOVA

2. Chi-square test of homogeneity

3. Chi-square test of independence

4. Chi-square test of goodness of fit
