Statistical Test: Pearson's product moment r (equals phi)
Statistical Measure: Refer critical ratio for phi to a table of the unit normal curve
Notes: Pearson's r in this case is mathematically equivalent ro a point biserial r; the tests are almost equivalent. Critical ratio for phi: McNemar, Q. Psychological Statistics. Fourth edition. New York: Wiley 1969. p. 227 Critical ratio for phi:
