✦ Synopsis

A modified exact test is proposed for 2 x 2 contingency tables. This test, which is based on a lees connervative definition of the concept of significance (STONE, 106s) is compared with a modified form of Pearson's X* test and with Tocher's randomized exact (UMPU) test. The sizes of the new test lie near the nominal 0.06 levels while those of the XI test usually exceed the nominal level, sometimen by a factor of 2 or more. The powcr of the modified test is usually close to that of the UMPU test.

Three approximations to the power function of the chi-square teat for the hypothema of 'no three factor interaction' in a 2 x2 x2 contingency table are introduced and compared. The firat method is baaed on the aampling distribution of the logarithm of the odds ratio, the second-on the noncentral dis
