c 2 . Test
c 2 . 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 H
0
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 c 2 . Test, enter the observed counts in a matrix. Enter
that matrix variable name at the Observed: prompt in the c 2 . 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] .
