2. A Phi coefficient is a non-parametric test of
relationships that operates on two dichotomous
(or dichotomized) variables. It intersects
variables across a 2x2 matrix to estimate
whether there is a non-random pattern across
the four cells in the 2x2 matrix. Similar to a
parametric correlation coefficient, the possible
values of a Phi coefficient range from -1 to 0 to
+1.
