c2.Test
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 Expected: prompt, enter the matrix variable name to
which you want the computed expected counts to be stored; default=[B].
