Statistical Test: Pearson's product moment r (equals point biserial r)
Statistical Measure: Refer critical ratio for point biserial r 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: McNemar, Q. Psychological Statistics. Fourth edition. New York: Wiley 1969.p. 219
