c2-Test (chi-square test; item C) computes a chi-square test for association on the two-
way table of counts in the specified Observed matrix. The null hypothesis H0 for a two-way
table is: no association exists between row variables and column variables. The
alternative hypothesis is: the variables are related.
Before computing a c2-Test, enter the observed counts in a matrix. Enter that matrix
variable name at the Observed: prompt in the c2.Test editor; default=[A]. At the
