Tables for Testing Significance In a 2 × 3 Contingency Table

The significance points for the 2 × 3 contingency table are tabulated in the cases where the three groups have equal numbers (=A) for A = 3 (1) 20 assuming fixed marginal totals. Four significance levels .05, .025, .01, .001 are tabulated, using the randomized test principle of Freeman and Halton. Examples of applications are given.
